nte States Patent 3,057,136 GRID Joseph H. Walter, l-laddarn, Conn., assignor to Emhart Manufacturing Company, Hartford, Conm, a corporation of Delaware Filed Aug. 11, 196i), Ser. No. 49,050 8 Claims. (Cl. 53-262) This invention relates to apparatus for automatically packing or loading charges of bottles, cans or like articles into cellular containers which may take the form of wood or cardboard cases having compartments or cells for individually holding the bottles or the like. More particularly, the invention relates to a grid usable in such apparatus for controlling and directing the gravity fall of charges of bottles or the like into the compartments or cells of a cellular container.

One object of the invention is to provide a grid of the type mentioned wherein the principal parts of the grid are particularly adapted for rapid and efficient assembly of the grid and the ready removal of grid parts for repair and replacement.

Another object of the invention is to provide a grid of the type mentioned wherein a large majority of the grid parts are of stamped sheet metal construction to the end that an economic advantage may be obtained in manufacture of the parts.

The drawings show a preferred embodiment of the invention and such embodiment will be described, but it will be understood that various changes may be made from the construction disclosed, and that the drawings and description are not to be construed as defining or limiting the scope of the invention, the claims forrning a part of this specification being relied upon for that purpose.

Of the drawings:

FIG. 2 is a plan view omitting some of the associated parts of the bottle packing apparatus in order to better illustrate the grid of the present invention;

FIG. 3 is an enlarged Vertical transverse section taken through the grid generally as indicated by the line 3--3 in FlG. 2;

FlG. 4 is a Vertical longitudinal section taken generally as indicated by the line 4-4 of FIG. 2;

FIG. 5 is an enlarged perspective view of an interior portion of the grid showing the detailed construction of some of the parts thereof;

FIG. 6 is an enlarged fragmentary section taken generally as indicated at 6-6 in FIG. 3;

FIG. 7 is an enlarged fragmentary section taken generally as indicated at 7-7 in FlG. 4; and

FIG. 8 is an enlarged fragmentary section taken generally as indicated at 8-8 in FIG. 3.

With the exception of the grid of the present invention, the bottle packing apparatus partially shown in FIG. 1 is conventional and need not be described in detail. In general, the said apparatus comprises an in-feed conveyor indicated generally at 10 which extends longitudinally in the apparatus and which transports bottles forwardly into parallel rows between stationary longitudinal guide plates 12, 12. The leading bottles in the rows of bottles between the guide plates 12, 12 are blocked and held in place on a dead plate 14 by engagement with the rear edge surfaces of a series of transversely shiftable longitudinal guide plates 16, 16 (shown with their front end portions broken away). The guide plates 16, 16 are shiftable transversely by means not shown from the position shown, wherein they block the rows of bottles between the plates 12, 12, to a position Wherein they are longitudinally aligned respectively with the guide plates 12, 12. ln this latter position of the guide plates 16, 16, the rows of bottles are advanced by line pressure from between the stationary guide plates 12, 12 and they slide forwardly between the guide plates 16, 16 along support or head rails 18, 18 which form a part of a grid 26 constructed in accordance with the present invention. When a predetermined and equal 'number of bottles (four bottles in the apparatus shown) has been advanced along each support rail 18, the front or leading bottle in each row actuates a switch-Operating slide 22. Switches, not shown, operated by the slides 22, 22 control the operation of the aforementioned Operating means for the shiftable guide plates 16, 16 and when said switches are operated as described by engagement of the front or leading bottles with the slides 22, 22, the said Operating means shifts the plates 16, 16 to the position shown in FlG. 1. Such movement of the plates 16, 16 causes the bottles to slide transversely off the support rails 18, 18 whereupon they fall by gravity through chutes or chute openings 24, 24 defined in the grid 20.

A charge of bottles, such as that shown in FlG. 1 With the bottles thereof in the course of descent through the chutes 24, 24 is received in a cellular container such as a compartmental wood case C. A roller top lift-table 26 in the packing apparatus is adapted to elevate cases in succession to a bottle receiving position beneath the grid 20. Said table is lowered to discharge packed or filled cases and to receive empty cases from an empty case in-feed conveyor indicated generally at 28. Cases are, of course, raised and lowered in properly timed relation with transverse shifting movements of the guide plates 16, 16 by suitable control means. Such control means are or may be conventional and a showing and description thereof is deemed unnecessary for a full understanding of the grid of the present invention.

From the foregoing, it will be apparent that efficient loading or packing of charges of bottles or the like in cellular containers is largely dependent on the effectiveness of the grid utilized in controlling the gravity fall of the bottles into their respective cells or compartments in the containers. ln the apparatus described generally above, the bottles in each row of a charge of bottles comprising several rows must be separated longitudinally and centralized longitudinally in their respective compartments or cells in the receiving container. The bottles are separated transversely by reason of the operation of the shiftable guide plates in conjunction with the support or head rails 18, 18, but is necessary that the bottles be centralized transversely with respect to the receiving compartments or cells. Obviously, a high breakage rate may be encountered if the bottles strike the upper edges of the receiving compartment or cell walls during descent as a result of improper or inadequate centralizing action. It is also desirable to regulate the rate of descent of the bottles in order to prevent breakage resulting from severe shock when they engage the base or bottom walls of their receiving cells or compartments.

The grid of the present invention efficiently fulfills all of the above-mentioned requirements and is yet of a desirably simple construction and is particularly well suited to inexpensive sheet metal stamping Operations in manufacture. Further, the parts thereof which are subject to wear and which may require repair or replacement at intermittent intervals are particularly adapted for ready removability.

All parts of the grid 20 shown in the drawings are supported in the bottle packing apparatus by spaced transversely extending front and rear support members indicated generally at 30 and 32 respectively. Preferably and as shown, the front and rear support members 30 and 32 are of like construction and each comprises upper and lower general'ly rectangular bars 34 and 36 connected together in parallel but vertically spaced relationship with each other. Two similar clamps 38, 38 interconnect the upper and lower bars 34 and 36 of the front support member 30 adjacent opposite ends thereof and two additional clamps 40, 40, like the clamps 38, 38, interconnect the upper and lower bars 34 and 36 of the rear support member 32 adjacent opposite ends thereof.

A representative c'lamp 38 is shown in section in FIG. 6 and it will be observed that it is generally U-shaped with a central spacer projection 42 disposed between and in engagement with the bars 34 and 36. A bolt 44 extends through a bore 46 in said projection 42 and nuts 48 and 50 on opposite sides of the bars 34 and 36 and the clamp 38 cooperates with a washer 52 to fixedly connect the clamp to the bars and to secure the bars in vertically spaced parallel relationship.

In FIGS. 1 and 2, it will be observed that the front and rear support members 30' and 32 are fixedly connected together in longitudinally spaced relationship by spaced longitudinal side support members 54, 54. Said side support members 54, 54 are connected with the front and rear support members 30 and 32 by means of suitable bolts 56, 56 and washers 58, 58 as best shown in FIG. 2. The bolts 56, 56 extend into suitably threaded openings in the ends of the side support members 54 and between the upper and lower bars 34 and 36 of the front and rear support members 30 and 32, and the washers 58, 58 are clamped against the outer surfaces of said bars by the bolt heads. Each of the side support members 54, 54 has a general'ly U-shaped hacking member 60 fixedly secured along its inner surface. The members 60, 60 are substantially shorter than the side support members 54, 54 and serve a purpose to be set forth hereinafter.

The front and rear support members 30 and 32, taken with the side support members 54, 54, may be said to constitute a supporting frame of the grid 20, all parts of the grid being supported thereon in the bo'ttle packing apparatus. Preferably, provision is made for the ready removal of the entire grid from the bottle packing apparatus. As shown, the grid is supported in the apparatus by two transversely spaced longitudinal frame members 62, 62 which project forwardly from the aforementioned in-feed conveyor 10. Resting on each of said frame members are front and rear grid support plates 64 and 66 which project transversely outwardly thereover. Inwardly projecting portions of the front and rear support plates 64, 64 and 66, 66 are fixedly connected with and entered respectively between the end portions of the upper and lower bars 34 and 36 of the front support member and between the end portions of the upper and lower bars 34 and 36 of the rear support member 32. Thus, it will be seen that the grid 20 may be removed from the bottle packing apparatus by moving the same longitudinally forwardly with the front and rear support plates 64, 64 and 66, 66 sliding along the frame members 62, 62.

The grid is re'leasably held in position in the bottle packing apparatus by means of two latching devices 68, 68 mounted respectively adjacent the front support plates 64, 64. struction, and each of said devices comprises a block 70 fixedly secured to a frame member 62 and carrying a spring pressed looking pin 72. The locking pin 72 is biased by a spring 74 into a suitable detent 76 in the adjacent end surface of the upper bar 34 of the front support member 30. Obviously, the grid 20 may be released for removal from the packing apparatus on manual retraction of the looking pins 72, 72 from their respective detents 76, 76.

As best il'lustrated in FIGS. 2 and 4, the bottle direct- The latching devices 68, 68 are of like coriing and controlling grid '20 includes front and rear transversely extending end plates 78 and 80. As shown, said plates are respectively attached to and supported by the front and rear support members 30' and 32 and they abut the side support members 54, 54 at opposite ends so as to be held against relative transverse movement. Preferably, attachment of 'the front and rear plates 78 and 80 to the front and rear support members 30 and 32 is accomplished by means of a series of bolts 82, 82 as shown, the front plate 78 being attached to the front support member 30' by six bolts 82, 82 which extend between the upper and * lower bars 34 and 36 of said support member and which are equally spaced transversely throughout the length of the member. The heads of the bolts 82, 82 are disposed inwardly or rearwardly of the front end plate 78 and the bodies thereof extend between the upper and lower bars 34 and 36 of the support member 30 and through bores 84, 84 in six blocks 86, 86 disposed outwardly or forwardly of the bars 34 and 36. Nu'ts 88, 88 threaded on the outer or forward ends of the bolts 82, 82 serve to clamp the blocks 86, 86 and the front end plate 78 in p'lace on opposite sides of the bars 34 and 36.

As best shown in FIG. 1, there are six blocks 86, 86, five of which carry switch-Operating slides 22, 22. The sixth block (86a) is associated with a bolt 82 adjacent one of the side support members 54. Said block 86a does not carry a slide 22 as no row of bottles is advanced toward the block over the grid 20.

The bolts 82, 82 securing the rear end plate 80 to the rear support member 32 are also six in number and they have their heads disposed inwardly or forwardly of the said rear end plate. Said bolts are equa'lly spaced transversely and are aligned longitudinally with the corresponding six bolts 82, 82 securing the front plate 78 to the front support member 30. The bodies of these six bolts extend rearwardly through bushings 90, 90, disposed between the upper and lower bars 34 and 36 of the rear support member 32, and through suitable apertures in a transverse guide support plate 92, said plate 92 being disposed rearwardly or outwardly of the rear support member 32. Washers 94, 94 and nuts 96, 96 serve to clamp the rear end plate 80 and the guide support plate 92 to opposite sides of the upper and lower bars 34 and 36 of the rear support member 32. The guide support plate 92, as best shown in FIG. 2 is provided with six equally transversely spaced notches 98, 98 for respectively receiving and transversely securing lo'wer front edge portions of the aforementioned stationary guide plates 12, 12.

Extending between the front and rear end plates 78 and 80 of the grid 20 are a series of six longitudinally and substantially horizontally extending ribs indicated generally at 100, 100. The ribs 100, 100 are equally spaced transversely and define a series of five Vertically open longitudinal spaces or Channels 102, 102 adapted for the downward passage of rows of bott'les. The ribs 100, 100 are detachably connected with and supported by the front and rear end plates 78 and 80 as will be described presently.

In their presently preferred form, each of the ribs 100 comprises a pair of similar elongated plates 104, 104 disposed in closely spaced parallel relationship. As best shown in FIG. 5, the plates 104, 104 of each rib 100 are connected together by a longitudinally spaced series of connectors or connecting means each comprising four rectangularly spaced spot weld areas 106, 106. At each end of each of the ribs 100 there is provided a generally U-shaped cutout which defines integral upper and lower end tabs 108 and 110, best shown in FIG. 4. The bs 100, 100 are arranged between the front 'and rear end plates 78 and 80 so that each upper end tab 108 rests on the head of a bolt 82, the ribs 100, 100 thus being supported vertically.

Means is also provided fo'r transversely securing each end portion of each longitudinal rib 100 and said means preferably comprises at least one pair of holding tabs associated with each end portion of each rib. As best shown in FIG. 5, an upper pair of holding tabs 112, 112 is operatively associated with each upper end tab 108 and a lower pair of holding tabs 114, 114 is operatively associated with each lower end tab 110. Preferably all of the holding tabs 112, 112 and 114, 114 'are formed integrally as shown and are bent longitudinally inwardly from the front and rear end plates 78 and 80. The tabs of each pair of tabs engage the adjacent end tab on a rib 100 on opposite sides whereby to secure said end tab and thereby secure the rib against transverse displacement. The outermost ribs 100, 100 are engaged by and additionally supported transversely by the aforementioned backing members 60, 60 as best shown in FIG. 2.

As best shown in FIGS. 2 and 5, each of the longitudinal ribs 100, 100 is provided along its upper edge portion with a longitudinal series of upwardly open transverse notches 116, 116. The notches 116, 116 are equally spaced longitudinally from each other in each rib, and the notches in each rib are approximately aligned transversely w'ith the corresponding no-tches in adjacent ribs 100, 100. Said notches serve to slidably receive and hold oppositely projecting ears 118, 118 formed on transversely arranged fingers indicated generally at 120, 120 and which will be described presently. The ears 118, 118 and the fingers are of course held against downward movement by the base walls of the notches, but said ears are free to move upwardly.

The fingers 120, 120 lare of similar construction and each may be described as bladelike and of double pronged construction, an upper portion or body 122 thereof being formed integrally with depending prongs 124, 124 thereof. More specifically, and in the preferred form shown, the fingers 120, 120 each comprise a pair of spring steel blades connected together in facing relationship at an upper portion as by rivets 126, 126. The lower portions of the spring steel blades, or the finger prongs 124, 124, diverge downwardly with respect to each other, and the upper portions of said blades, or the body 122 of each finger, are provided with a generally V-shaped insert 128. Substantially below the ears 118, 118 thereon, the body 122 of each of the fingers 120, 120 is engaged on opposite sides by a pair of transversely bent holding tabs 130, 130. The tabs 130, 130 are formed integrally on the plates 104, 104 of each rib 100 and they serve to secure the fingers 120, 120 against longitudinal displacement.

Referring particularly to FIG. 2, it Will be observed that the several transversely 'arranged fingers 120, 120 cooperate with the longitudinal ribs 100, 100 to partially form the aforementioned Vertical chutes or chute openings 24, 24. The chutes 24, 24 in the longitudinally extending series of four chutes in each longitudinal channel or space 102 are adapted for the downward passage o'f individual bottles in a row of bottles descending through said channel or space. The V-shaped inserts 128, 128 constitute means for separating the bottles lin such a row and for centralizing the same longitudinally and to some extcnt transversely in their respective chutes. Note also that the lower portions of the individual blades of each finger 120, or the prongs 124, 124 thereof, extend longitudinally toward the center lines of longitudinally adjacent chutes. Said prongs serve to control the gravity fall of bottles through the chutes and guide the bottles into their respective cells or compartments in the receiving contrainer.

The chutes or chute openings 24, 24 are also partially defined by longitudinally arranged depending bladelike fingers indicated generally at 132, 132. As best shown in FIG. 5, each of the fingers 132, 132 comprises a pair of spring steel blades having lower portions or prongs 134, 134 which diverge downwardly and flat upper portions 136, 136 disposed in face-to-face relationship. Said upper portions 136, 136 may be connected together as by riveting or they may be independent as will be seen. Formed at the upper edge port'ion of each finger 132 are two longitudinally and oppositely projecting ears 138, 138.

The fingers 132, 132 are ararnged longitudinally as stated and their upper portions 136, 136 are entered between adjacent plates 104, 104 of the four innermost longitudinal ribs 100, 100. As best shown in FIG. 5, each connector or group of rectangularly spaced spot weld areas 106, 106 on said ribs may be said to generally define in Cooperation with the rib plates a longitudinal vertically open slot. The fingers 132, 132 are slidably entered and are movable upwardly respectively in said slots with their oppositely projecting longitudinal e'ars 138, 138 resting on the two uppermost spot weld areas 106, 106. The two lowermost spot weld areas 106, 106 engage or at least approximately engage the body portions 136, 136 of the fingers 132 at opposite sides to secure the fingers against longitudinal movement. Thus, the uppermost spot weld areas 106, 106 of each connector and the ears 138, 138 on the fingers may be said to constitute a stop means securing the fingers against downward movement in their respective slots.

From the foregoing it will be apparent that each of the six centrally located chutes or chute openings 24, 24 has four finger blades or prongs associated therewith. Two prongs 124, 124 of longitudinally adjacent transversely arranged fingers 120, extend longitudinally toward the Vertical center line of each of said chutes `and two prongs 134, 134 of transversely adjacent longitudinally arranged fingers 132, 132 extend transversely toward the said Vertical center lines of said chutes. T hus, bottles passing do-wnwardly through the chutes will be guided toward the centers thereof and deposited centrally in the cells or compartments of a receiving container disposed beneath the grid 20.

As mentioned, the body portions 136, 136 of the fingers 132, 132 may be interconnected or they may be independent of each other. :It will be apparent that such body portions can be held together in face-to-face relationshipl with single pronged fingers 132a as best shown in FIG. 3,.,

the lack of a need for double pronged fingers being apparent. The single pronged fingers 132a, 132a may be identical with the double pronged fingers 132, 132 or, more specifically, with one half or one blade thereof. Said fingers may be held between the plates 104, 104 of said outermost ribs 100, 100 in a manner identical with that described for the four innermost ribs 100, 100 and the fingers 132, 132.

Referring again to FIG. 2, it will be observed that each of the chutes 24, 24 in the outermost transverse or front and rear rows of chutes 24, 24 has a single pronged finger 140 associated therewith. The fingers 140, 140 are similar to the fingers 132z, 132a and they are disposed in spaced rows of five between the front end plate 78 and the front support member 30 and between the rear end plate 80 and the rear support member 32. As best shown in FIG. 5, each finger 140 is provided with a pair of ears or tabs 142, 142 at an upper end portion thereof. Said ears or tabs are bent longitudinally so as to engage the upper surface of the adjacent support bar 34 and prevent the finger from sliding downwardly between the adjacent end plate and bar.

The aforementioned support rails 18, 18 which vertically hold rows of bottles as they are advanced between the shiftable guide plates 16, 16 take the form of elongated wear resistant heads or head rails for the longitudinal ribs 100, 100. Accordingly, there are six such rails provided in the embodiment of the invention shown.

Each support or head rail 18, in addition to its function of supporting a row of bottles during advance of the bottles and prior to shifting of the guide plate 16, 16, serves as a holding device. That is, each head rail 18, associated with a rib 100, serves to engage the ears 118, 138 and to hold the fingers 120, 120 and 132, 132 associated with said rib against upward movement and in place in their respective notches and slots. In FIG. 5, the ears 118, 118 on the transverse fingers 120, 120 associated with the rib 100 shown are engaged and held in their respective notches 116, 116 by a head rail 18. Similarly, the fingers 132, 132 associated with said rib are engaged and held in their respective slots between the spaced plates 104, 104 of the rib by the said head rail.

Six equally spaced longitudinal slots 144, 144 in the front end plate 78 and six similar slots 144, 144 in the rear end plate 80 receive end portions of the head rails 18, 18 and secure the same against relative transverse movements. As best shown in FIG. 4, the aforementioned blocks 86, 86 are each provided with a suitable recess 146 for receiving an end portion of a head rail 18. A transverse looking rod or wire 148 (FIGS. 2 and 4) threaded through transversely aligned openings in the front end portions of the head rails 18, 18 prevents rearward displacement of the head rails by engagement with an upper portion of the outer or front face of the front end plate 78. Short transversely projecting holding pins or beads 150, 150 formed on the rear end portions of the head rails 18, 18 project beneath a short horizontal fiange 152 formed integrally on the aforementioned guide support plate 92. Said plate has six equally spaced slots 154, 154 which respectively receive rear end portions of the head rails 18, 18.

'From the foregoing, it will be apparent that the grid of the present invention is particularly well suited to low cost quantity production by reason of the provision of a large majority of parts which may be readily formed of sheet metal in conventional cutting and bending press operations. All of the aforementioned fingers, the longitudinal ribs 100, 100, and the front and rear end plates 78 and 80 are obviously well suited to such manufacturing Operations.

The manner in which the various parts of the grid 20 can be readily removed for repair and replacement should be apparent from the foregoing and only a brief descrption is necessary. The grid is preferably first removed bodily from the bottle packing apparatus by releasing the aforementioned latching devices 68, 68. Thereafter, the head rails 18, 18 may be quickly removed by withdrawing the holding rod or Wire 148 and sliding the said rails rearwardly. With the head rails removed, any one or all of the fingers in the grid may be conveniently and quickly removed merely by lifting the same vertically from its respective notch or slot. Replacement of parts after repair or substitution of new parts may also be readily accomplished with substantial savings in time and eifort.

The combination in a grid as set forth in claim 6 wherein said connectors between the rib plates each take the form of four rectangularly spaced spot weld areas, and wherein the bladelike fingers of said second group each have a pair of oppositely projecting ears at an upper portion thereof, the ears On each finger serving respectively to engage the two uppermost spot weld areas of an associated connector and to thereby secure the finger against downward movement when the finger is entered vertically in the 'space between the rib plates and between the four spot weld areas of lthe connector, and the opposite edges of each finger respectvely engaging the two lowermost spot weld areas of the connector for longitudinal support when the finger is so located.

8. The combination in a grid as set forth in claim 7 wherein each plate of each rib is provided with a pair of integral transversely bent holding tabs adjacent each transversely arranged finger associated with the plate, the tabs of each pair of tabs being adapted respectvely to engage the adjacent transverse finger on opposite sides thereof and substantially below the ears thereon whereby to secure the finger against longitudinal movement.
