Apparatus for assembling tubular cartons
US 3835619 A
Abstract
The lids of tubular cartons are assembled and secured into the ends of paperboard tubular cartons by disposing them in a recessed block against a prominent surface which is spaced from the sidewalls of the recess by an annular groove. Tabs, provided on the lids, engage into notches extending from the recess into the wall of the block to maintain the peripheries of the lids evenly spaced within the annular groove. When the tubular walls are pushed into the annular groove around the lids, the tabs are inwardly deflected through the notches within the walls. The tabs are secured to the walls by power-operated staplers which react against anvils disposed within the prominent surface. The block has its recess facing up in a manual form of the apparatus for assembling the first lid within the walls. The lids are manually laid on the prominent surface with their tabs inserted in exposed notches, before manual insertion of the tubular wall around it. The staplers are actuated by microswitches in the base of the annular groove contacted by the leading edge of the tubular wall. The second or carton sealing lid is assembled by a substantially automatic version of the apparatus in which the block is inverted with its recess facing down. The filled cartons are fed upwardly upon a pneumatically operated elevator. Lids are previously inserted within the recess from a lid storage magazine by a reciprocating carriage which pushes against the tabs of the lids to successively slide them through a slit in the side of the block against the prominent surface.

22 Claims, 14 Drawing Figures APPARATUS FOR ASSEMBLING TUBULAR CARTONS CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of copending applications for US. Pat. Ser. No. 302,264 filed Oct. 30, 1972 and Ser. No. 328,479 filed Jan. 31, 1973 by this same inventor.

BACKGROUND OF THE INVENTION Tubular containers of fairly thick flexiblematerial, such as thin paperboard are very effective for packaging bagged snack food articles, such as pretzels and potato chips. Assembling apparatus to facilitate and expedite assembly of the lids of such cartons is highly desirable. An object of this invention is to provide such an apparatus which is simple and economical and efficient in operation.

SUMMARY The lids of tubular cartons are assembled and secured into the ends of paperboard tubular cartons by disposing them in a recessed block against a prominent surface which is spaced from the sidewalls of the recess by an annular groove. Tabs, provided onthe lids, engage into notches extending from the recess into the wall of the block to maintain the peripheries of the lids evenly spaced within the annular groove. When the tubular wall are pushed into the annular groove around the lids, the tabs are inwardly deflected through the notches within the walls. The tabs may be secured to the walls by power-operated staplers which react against anvils disposed within the prominent surface. The block may have its recess facing up in a manual form of the apparatus for assembling the first lid within the walls. The lids are manually laid on the prominent surface with their tabs inserted in exposed notches, before manual insertion of the tubular wall around it. The staplers may be actuated by microswitches in the base of the annular groove when they are contacted by the leading edge of the tubular wall. The second or carton sealing lid may be assembled by a substantially automatically version of the apparatus in which the block is inverted with recess facing down. The filled cartons may be fed upwardly upon a pneumatically operated elevator type of pusher. Lids may be previously inserted with the recess from a lid storage magazine by a reciprocating carriage which pushes against the tabs of the lids to successively slide them through a slit in the side of the block against the prominent surface. The tapered mouth of the block is thus unbroken. The slit extends outside of the annular groove into the wall of the block to hold the lids suspended by their tabs within the recess. The lid-locating notches in the slit block are defined by: the terminal ends and outer sides of the slit and the top ends of the pusher rods on the reciprocating carriage. After the tabs are stapled to the wall, an ejecting finger assembly may eject the cartons. The carton elevator, reciprocating lid-feeding carriage and ejecting finger assembly may be operated by pneumatic motors. The stapler may be electrically actuated when the reciprocating carriage reaches its outward extremity of the travel. The pneumatic motors may have two operating conditions. Their control system may include a time delay switch which returns them to the initial normal condition a predetermined time after actuation to the operating condition, such as in from 4 to 12 seconds. In the initialformal condition .prior to actuation: the carton elevator is down, the reciprocating carriage is in the inserted condition and the ejecting finger assembly is retracted. In the operating position, the elevator has pushed a carton into the block and the reciprocating carriage is being withdrawn. The carriage strikes the staple operating switch at its outward extremity of travel to secure the tabs of the lids within the tubular walls. The carriage may actuate the ejector motor during the beginning of inward movement to cause it to strike the lid and eject the carton after the lid is stapled. Prior to ejection, the carton elevator has been lowered on its return by the time delay switch to the initial normal condition. The reciprocating carriage may insert the next lid within the recess in the block when it moves back to the initial normal position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 14, is shown a substantially automatic apparatus 10 for assembling lids 12 and tubular walls 14 into tubular cartons 16. Apparatus 10 includes a recessed block 18 shown in detail in FIGS. 5-7 having an internal recess 20 surrounded by an internal sidewall 22 and having a prominent surface 24 disposed within recess 20 and spaced from wall 22 by annular groove 26.

The primary function of partially automatic apparatus shown in FIGS. 1-10 and essentially manual apparatus 10A shown in FIGS. 11-14 is to assemble lids 12 and tubular walls 14 into tubular cartons 16, such as those described in the aforementioned copending US. patent application. Initial reference to substantially manual apparatus 10A facilitates a description of the essential features of this invention.

In FIGS. 11-14 is shown block 18A which is disposed with recess 20A facing up. Lids 12A are laid upon prominent surface 24A as shown in FIG. 12 with their tabs 30A similar to tabs 30 (shown in FIG. 10) inserted in notches 32A to evenly space their peripheries 34A from internal wall 22A of recess 20A. This maintains peripheries 34A' in position for insertion of tubular walls 14A into annular groove 26A around them. The insertion of tubular walls 14A into grooves 26A inwardly deflects tabs 30A through notches 32A into tubular grooves 26A as shown in FIGS. 13 and 14. Tapered or conical section surface 36A leading into recess 20A helps guide tubular walls into grooves 26A. A pair of power-operated staplers 38A are disposed outside of notches 32A. A pair of microswitches 40A for actuating staplers 38A are also positioned diametrically opposite each other in the base of groove 26A. A shaped anvil 41A is mounted within prominent surface 24A in line with staplers 38A and it has a pair of double concave heads 44A.

The assembly of a first lid or bottom 12A within a tubular wall 14A is commenced as shown in FIG. 12 by laying a lid 12A on top of prominent surface 24A with tabs 30A engaged within notch 32A. The triple folded rim 42A of tubular wall 14A is then urged downwardly into groove 26A which deflects tabs 30A through notches 32A within tubular walls 14A. When the bottom of rim 42A strikes microswitch 40A, stapler 38A is actuated to move stapling head 46A into contact with rim 42A, and a staple 39A is thereupon forced through rim 42A of tubular wall 14A and inwardly bent tabs 30A. Impingement of the points of staple 39A on double concave head 44A of anvii 41A closes the staple around rim 42A and tab 30A. Stapler head 46A is actuated to move into firm contact against the assembled parts by any convenient type of actuation, such as manual or electrical. Staplers 38A may accordingly be either pivoted or have a solenoid-operated stapling head.

After tubular walls 14A and lower lids 12A have been assembled to each other as shown in FIGS. 11-14, contents are inserted within them, such as polyethylene bag 50, shown in FIG. 5, containing for example pretzels or potato chips. Apparatus 10 shown in FIGS. 1-10 assembles an upper lid 12 on carton 16 and seals it. Apparatus 10 includes a recessed block 18, similar to that described in FIGS. 11-14, but it is associated with various automated components which facilitate the final assembly.

Apparatus 10 has block 18 as shown in FIGS. 5-7 with recess 20 facing downwardly. Lid storage magazine 52 is mounted alongside block 18, and reciprocating carriage 54 successively inserts lids 12 from it into block 18 through slit 56 shown in FIG. 7. Cartons 16 are inserted into cavity 20 andurged into grooves 26 by a pusher means 58 comprising a plunger operated elevator including operating plunger 60 and platform 62.

A pair of staplers 38 shown in FIGS. 4 and 5 are mounted on the side of block 18 outside of internal notches 32 (later described). Staplers 38 are actuated by microswitch 40 disposed in the path of travel of pro- 5 jection 64 on reciprocating carrige 54, which actuate staplers 38 in a manner later described.

Ejecting finger assembly 66 is mounted above block 18 and as shown in FIG. 7 includes a pair of ejecting fingers 68 mounted on head 70 connected to ejecting plunger 72. Reciprocating carriage 54 is also driven by a reciprocating plunger 74. Plungers 60, 72, and 74 are all for example of the pneumatic type operated by compressed air alternatively provided at both ends of the plungers to drive them in either of two directions of travel. The plungers are operated by a timed pneumatic switching device 76 which is actuated by a starting control 78. Time delay pneumatic switching device 76 is for example a two-condition control device operating on a time delay such as from 4 to 12 seconds. 8 seconds is for example a convenient operating period. Air is supplied to control device 76 through filter 80 and gauge 82 from a source of compressed air. The first condition of operation of device 76 is the operating condition which occurs when operating control 78 is actuated by pressing down on knob 84. The connections through which air flows in the operating condition are labelled by numeral I in the drawing as well as by arrows which indicate the direction in which air flows in the indicated plunger during this phase of operation. During the operation condition, plunger 60 moves upwardly to raise elevator platform 62 and cartons 16 upon it into recess 20 in block 18. At the same time, plunger 74 is actuated to the left, thus moving carriage 54 to the outer extremity of travel away from block 18 through the connection of carriage S4 to plunger 74 by L-shaped bracket 86. Valve actuating shoe 89 at the bottom of bracket 86 contact a pair of pneumatic valves A and B on air switch 87 which are attained to the A-1 and 8-] sides of ejection plunger 72. Air switch 82 is not, however, actuated in the outward stroke of carriage 54, because compressed air is not supplied to it in condition I. As previously mentioned, bracket 86 carries projection 64 which contacts microswitch 40 to operate staplers 38 when carriage 54 reaches its outward limit of travel, to apply staples 39. Pneumatic valve controls A and B and actuating shoes 89 are constructed and arranged to operate ejecting finger assembly 66 when compressed air is supplied to switch 87 during the beginning of the return movement of carriage 54. Valve contact A moves finger assembly 66 to the position shown in FIG. 7 in which fingers 68 move downwardly through passages 88 in block 18 to force an assembled carton 16 downwardly out of recess 20. Then ejecting finger assembly 66 is rapidly retracted. This rapid forward and backward movement of ejecting finger assembly 66 is accomplished by close successive actuation of valve operating elements A and B which first deliver air during the beginning of phase II to the top of plunger 72 to move it in the A-l direction downwardly and then back upwardly in the B1 direction as shown by associated arrows near plunger 72 in FIG. 1.

Just as carriage 54 reaches its outer limit of travel, timed control device 78 has switched over to the initial or normal condition in which air is supplied through fittings designated by numeral II to the indicated ends of plungers 60 and 74 to drive these plungers in the directions indicated by the arrows near numerals II. This rapidly lowers platform 62 away from under carton 16 after microswitch 40 has actuated staplers 38. The lag in pneumatic operation by controls A and B to operate ejecting plunger 72 provides enough time for elevator 62 to move downwardly out of the way of an ejected carton 16 before ejecting plunger 72 is rapidly moved down and up. This occurs during the beginning of movement of carriage 54 back to the right during which it picks up a lid 12 from lid storage magazine 52.

The lid inserting function is shown in FIGS. 1, 2, 3, 8 and 9. Lids are stored in a stack in front of rear vertical guide bar 90 with tabs 30 aligned between angle rods 92 mounted on lateral surfaces 94 on both sides of lid support surface 96. Lid support surface 96 is disposed below lateral surface 94 approximately the thickness of a single lid 12. Lid support surface 96 is separated from lateral surfaces 94 by pair of slots 98 within which are disposed rods 100, as shown in FIGS. 3, 8 and 10. Rods 100 are confined to slide in slots 98 by brackets 99. The tops of rods 100 are at the same level as lateral surfaces 94. The bottom lid 12 in magazine 52 thus rests upon lower lid support surface 96 and its tabs 30 thus drop freely below the bottoms of vertical angle guides 92. This permits the front ends of rods 100 to pick up the tabs 30 ofa lower lid 12 as shown in FIG. 2 and push it to the right under the bottom edges of angle rods 92 toward block 18.

As shown in FIGS. 7 and 10, a slit 56 is provided through the side of block 18 in alignment with prominent surface 24 to permit a lid 12 to be inserted through block 18 against prominent surface 24. Slit 56 is slightly wider than annular groove 26 for example, by the extension of tab 30. The insertion of tabs 30 in the ledges provided by the portions of slits 56 within recess thus suspends lids 12 within recess 20 in position for engagement by upwardly moving tubular walls 14. Notches 32 are defined by: the forward extremity 103 of slits 56, the outer side 105 of slits 56 and the tip end 102 of rods 100. Tip ends 102 of rods 100 are arrested by the inner ends 101 of slots 98 within block 18 at the sides of slits 56. The tapered mouth 36 leading into recess 20 is thus unbroken and notches 32 are internally concaled.

FIG. 4 shows a lid 12 within recess 20 in position for engagement by an upwardly moving open topped carton l6. Notches 32 are disposed in block 18 within slits 56 and thus permit tabs 30 to be bent inwardly, from the position at which they are arrested by stop surfaces 103 within slits 56, and pulled out of slits 56 into annular groove 26.

FIG. 5 shows the engaged position of wall 14 at its folded rim 42 within groove 26 after tab 30 has been bent inwardly within it after being pulled out of internal notches 32. After full insertion of rims 42, staplers 38 have their heads 46 moved into engagement with tabs 30 to fire staples 39 through rims 42 and tabs 30 against anvil heads 44 to close them.

As shown in FIGS. 1 and 2, staplers 38 include wire supply reels 104 which supply staple material 39 through guide tubes 106 to stapling heads 46 by actuation of feed rools 108 and pulley drives 110. Staplers 38 are any convenient power-operated staplers and the configuration shown is merely an illustrative example.
