5 Claims. (Cl. 53-124) This invention relates to improvements in the art of compression bundling, and more particularly to an improved method of and apparatus for effectively bundling a plurality of uniform small packages or units.
Many commodities are packaged in individual small packages or units for individual sale by the retailer. However, it is customary for the manufacturer or processor to ship a multiple number of the smaller packages, which are identical, in large corrugated or fiberboard cartons, as it was felt that it was necessary to protect the inner packages or units by the heavy walls of the cartons. The retailer, upon receiving a large carton of the product containing a multiple number of the smaller packages, would open the carton, price mark the individual packages, and place a number of the same on his shelves for retail sale. The shipping case or carton in which the smaller packages or units were packed would remain in its original size and form, and storage space would have to be found therefor as some of the packages might remain therein for future display and sale.
Not only was it expensive to provide heavy corrugated or fiberboard cartons or shipping cases for the product packages, but storage space for the same presented a problem. With the above in mind, therefore, it is a primary object of the present invention to provide an improved method of and apparatus for compression bundling whereby a multiple number of identical small commodity packages or units can be wrapped in a heavy sheet of paper or single-faced or double-faced corrugated board, which wrapping material is applied about a predetermined number of the smaller packages or units, while the latter are under compression in all directions, whereby, through the compression applied to the multiple number of smaller packages during the wrapping operation an extremely rigid and strong outer package or bundle is produced which will satisfy shipping, insurance, and Interstate Commerce Commission requirements.
A further object of the invention is to provide a method of and apparatus for compression bundling wherein the wrapped inner packages or units, kept under compression in all directions during the wrapping operation, impart to the completed bundle, cellular or honeycombed characteristics, providing a finished bundle or package of great strength, but of low weight, and which utilizes as its wrapping sheet inexpensive heavy paper or singlefaced corrugated board instead of a heavy and expensive carton or shipping case.
A further object of the invention is to provide, in a compression bundling apparatus, conveyor means for advancing a predetermined number of juxtapositioned similar small packages or units, which will constitute the ultimate bundle, together with means for initially compacting the loose packages on the conveyor, followed by means for compressing the units making up the bundle, both widthwise and lengthwise while being advanced.
A further object of the invention is to provide, in a compression bundling apparatus, means on an elevator to hold the individual units or packages making up a bundle,
2,962,848 Patented Dec. 6, 1960 in a compressed condition while being projected adjacent a flexible wrapping sheet to be wrapped therein into bundle formation, all while the individual packages are maintained in a compressed condition.
A further object of the invention is to provide, in an apparatus for compression bundling, means for holding the unit packages making up a bundle under compression while a sheet of wrapping material applied thereto is being folded and sealed about a predetermined number of the unit packages.
A further object of the invention is to provide an improved method of compression bundling a plurality of grouped, unit packages wherein the grouped unit packages are maintained under high compression while being advanced and presented to a sheet of flexible wrapping material, and during the complete application and sealing of the wrapping material, to provide an ultimate bundle A further object of the invention is to provide, in the art of compression bundling, a compact but strong bundle of a plurality of unit packages in which the wrapping sheet for the bundle is of inexpensive flexible material, susceptible of being easily opened for the removal of any desired number of the unit packages, following which the wrapping sheet may be folded and secured in more compact condition about the remaining unit packages in the bundle for convenience and for the saving of space in storage.
Other objects of the invention are to provide an improved method of and apparatus for compression bundling which are expeditious but simple, and which are well adapted for the purposes described.
With the above and other objects in view, the invention consists of the improvements in the art of compression bundling, including all of its parts, combinations and steps, as set forth in the claims, and all equivalents thereof.

Fig. 6 is a transverse sectional view taken approximately along the line 6-6 in Fig. 2; and
Fig. 7 is a transverse fragmentary sectional view through a completed compressed and wrapped bundle of a two tier type.
Referring now more particularly to the drawings, it will appear that the infeed extent of the improved compression bundling machine is shown in Fig. 1. The numeral 10 designates a flat bed plate whereon, at a station indicated A, a predetermined number of identical unit packages 11 of a commodity are deposited by conveyor means in adjacent but loosely arranged rows. During the continuous operation of the machine this deposit of a predetermined number of unit packages upon the bed plate at station A is continuous and each group of the unit packages is advanced horizontally in the direction of the arrows in Fig. l by a conventional power driven conveyor which includes spaced apart flight bars 12, 12(a),,12(b), 12(6), 12(d), etc., the ends of the flight bars being attached to an endless conveyor chain 13. As the group of unit packages 11 is advanced by a flight bar of the conveyor from station A to station B, the flight bar 12(a) pushing against the group of unit packages causes the same to enter between transversely spaced apart guide rails 14 supported from the upper part of the bed plate which serve to initially compact the loosely arranged group of unit packages 11 both lengthwise and widthwise of the group. At station C there are mounted along opposite margins of the bed plate 10, driven compression belts 15 which are guided by rollers 16 mounted on upright axes. As is shown more clearly in Fig. 3 the belt engaging rollers 16 are so arranged that the entrance or mouth formed between the pair of belts 15 is relatively wide but the effective space there-between becomes narrower and more restricted so that as the group of unit packages 11, reaching station C, is advanced by the conveyor flight bar 12(b the toed-in arrangement of the compression belts 15 forces the unit bundles 11 together and very substantially compresses the group lengthwise. Any suitable means, as adriven shaft 17 carrying gears 18 meshing with gears 19 on certain of the belt-carrying rollers 16, will cause said rollers to be driven to move the endless compression belts 15.
With reference to Fig. 1 and adjacent the restricted or toed-in ends of the compression belts 15, the bed plate 10 aligns with the flat platform portion of a vertically movable elevator 20 and which receives the group of unit packages 11 which have been brought together in tightly compressed condition by the instrumentalities at stations B and C. To maintain the group of packages under compression while on the elevator 20, the receiving plate portion of the latter, at its side margins, is equipped with spring loaded side plates 21, wherein the spring arrangement is shown schematically in Fig. l, but in more detail in Fig. 4.
The elevator 20 is of the type which is conventional in wrapping machinery to move an article to be wrapped into juxtaposition to a sheet of wrapping material and the wrapping instrumentalities. In the present embodiment the wrapping and outfeed extent of the improved compression bundling apparatus has the inner end of its bed plate 22 positioned above and slightly to the right (relative to Fig. 1) of the elevator 20. The wrapping and outgoing extent of the machine is shown in Fig. 2 and it should be understood that in actual practice the elevator 20, with agroup of compressed unit bundles 11 thereon, maintained in compressed condition by the spring-loaded side plates 21, moves vertically upwardly from the position of Fig. 1 to a position adjacent the inner end of the bed plate 22 in Fig. 2. However, in Fig. 2 the elevator 20 has been lowered or retracted, but isaid elevator, before commencing its descent, is shown in When the elevator 20 reaches its upward limit of travel so as to align with the. inner end of the bed plate 22 of the upper portion of the mechanism the unit packages 11 are still maintained in a state of compression by the spring-loaded plates 21. The numerals 23 indicate air cylinders which are automatically operated in timed relation to the movements of the elevator 20 to forcefully project pistons 24 against the ends of the compressed unit packages on the elevator platform and as soon as the engagement is made by the pistons 24, as shown in Fig. 4, the elevator is retracted or lowered so that the situation shown at the left hand end of Fig. 2 attains.
In this position the longitudinal margins of the compressed group of unit packages 11 are tightly engaged by angled, spring-loaded ejector buckets 25 which engage the longitudinal margins of the group of unit packages after a sheet 26 of wrapping material has been fed into the mechanism by conventional means to cover the top of the group of unit packages and to drape over the sides and ends thereof. To avoid obscuring portions of the drawing the spring-loading means for said buckets 25 have been omitted at the primary wrapping station D but are shown at the advanced wrapping stations E and F. Also, to prevent obscuring portions of the assemblage the wrapping sheet has been omitted from Figure 4. In Figure 2, the numerals 27 indicate conventional rear folders for a sheet wrapping mechanism and the same, by means common in the art, are projected from the inactive position of Fig. 2 to an advanced position toward the right to cover the entire end portions of the group of unit packages and to hold the wrapping material sheet 26 over the same, while the spring-loaded buckets 25, when applied aid in folding the sides of the sheet 26 downwardly along the longitudinal margins of the group of unit packages 11. These wrapper folding operations take place at station D as the elevator 26 descends and the projected operative position of the rear folders 27 is shown in Fig. 5, wherein the slots 28 accommodate the pistons 24. The pistons 24 of the air cylinders 23 remain in their projected, package-end engaging positions until the rear folders 27 are in the operative package overlapping position shown in Fig. 5.
After the operations are performed at station D the group of compressed unit packages 11 is advanced along the bed plate 22 toward the right relative to Fig. 2 to station E by a conventional conveyor (not shown). At station E the wrapping sheet 26 is rather completely folded about the group of unit packages 11 which are maintained under compression by the buckets 25 and the group of compressed unit packages, as thus wrapped, enters between a pair of transversely spaced apart springloaded Wrapper folding bars 29. In advancing from station E to station F the end folds of the wrapping sheet are run through conventional creaser rollers 30 which maintain compression in the completed bundle.
From station F the Wrapped bundle, wherein the unit packages are maintained under compression, are advanced to station G which illustrates a completed compressed wrapped bundle of unit packages. Conventional means then advance the fully wrapped bundle from station G to station H where discharge belts 31 are provided which hold the end folds of the wrapping sheet 26 while the glue or adhesive previously applied thereto is setting. The discharge belts operating at station H carry the completely wrapped and compressed bundles to a suitable discharge or collection station.
In the finished bundle all of the unit packages 11 therein are maintained by the folded and sealed wrapping sheet 26 in compressed condition. This gives great strength to the final bundle and prevents buckling or misalignment of any of the unit packages 11 therein so that the surface portions of the wrapped bundle always remain in a flat undented condition.
While Figs. 1 and 2 illustrate a plurality of unit packages 11 wrapped to produce a single tier bundle, it is obvious within the purport of the present invention, that the final bundle may comprise two or more tiers of aligned and compressed unit bundles, as shown in Fig. 7. In carrying out the improved method of compression bundling, many instrumentalities conventional in wrapping machinery are employed, but the essence of the invention is maintaining the group of unit packages under tight compression in several directions during all of the stages and particularly during presentment of the group of unit packages making up the bundle to the sheet of wrapping material and maintaining the compression on the unit packages while the wrapping sheet is applied and thereafter during the folding and sealing of the Wrapping sheet. By keeping the bundle in compression at all times the unit packages making up a bundle are held in close and compact alignment to produce, in the ultimate bundle, a cellular or honeycombed structure whereby the ultimate bundle, even though wrapped with a paper sheet, possesses great strength and rigidity.
From the foregoing description it will be seen that the improved method of and apparatus for bundling under compression a plurality of uniform small unit packages subjects the unit packages to substantial pressure and compacting in several directions while each group of unit packages is being advanced for presentation to the sheet of wrapping material. The compression is maintained during the application of the wrapping material and the folding and sealing thereof. The completed bundles possess great strength and rigidity and, notwithstanding the fact that relatively light weight wrapping material is used as compared with heavy corrugated board cartons, the bundles will satisfy all requirements.
The apparatus is relatively simple, is expeditious in operation, and the improved method of compression bunding is higly practical.
