7 Claims. (Cl. 53-124) This invention relates to a closing machine for cartons, and more particularly to an improved machine of this type which is especially adapted, in connection with cartons lled with produce, such as lettuce, and the like, to buttress all four of the side walls of the carton while causing the closure iiaps of the carton to be moved to a closed position for sealing.
The subject apparatus constitutes an improvement over the apparatus disclosed in a commonly owned co-pending application, Serial Number 506,937, iiled May 9, 1955. Both the apparatus disclosed in said co-pending application, and the improved apparatus forming the subject matter of the present application are adapted to be embodied in a field crop packing machine of the type which is employed to harvest and pack eld produce, such as lettuce. The machine of said co-pending application operates to fold a pair of oppositely disposed side walls of a lettuce-filled carton against outward bulging asl it moves the closure aps of the carton to a closed position for sealing. It is now required that such lettuce-filled cartons have all four side walls thereof retained in against outward lbulging when the closure flaps are closed for sealing.
The essential object of the present invention is to ernbody means in the machine of the co-pending application whereby said machine may be adapted to act on all four side Walls, instead of merely two, during the carton closing operation.
(lther objects and advantages of the invention will be apparent from the following description taken in conjunction with the drawings forming part of this speciiication, and in which:
Figure 1 is a view in perspective of the carton closing machine of the present invention, with one of the closure ap presser plates being shown in dotted outline to prevent masking of the machine parts disposed behind said presser plate;
Figure 2 is a view taken along lines 2-2 of Figure l of the right half of the machine;
Figure 3 is a view similar to that of Figure 2, but showing the carton side holding elements in operative position;
Figure 4 is a detail View taken along lines 4-4 of Figure 2;
Figure 5 is a detail view taken along lines 5--5 of Figure 2; and
Figure 6 is another detail view taken along lines 6-6 of Figure 3.
With immediate reference to Figure l, the machine comprises a rectangular frame 10 having integral therewith legs 12, a pair of channel members 14 secured to frame 10 at oppositely disposed sides of the top thereof, a plurality of conveyor rollers 16, and pair of oppositely disposed carton closing assemblies indicated generally at 18 and 20.
The carton closing assembly 18 comprises a vertically disposed plate 22, a plate, a plate 24 having a hinge con- ICE ing into sleeve members iixedly secured to frame 10 and being adjustably secured thereto, as by set screws 32. The plate 22 has also secured thereto a bar 34 which is provided at its lower end with means for pivotally mounting the lower end of a two-way acting hydraulic cylinder 36. The piston rod 38 of cylinder 36 is pivotally secured, as by pin 4t) to an arm 42, said arm having a forked end 44 which is Xedly secured, as by welding, to plate 24.
The carton closing assembly 20 comprises plate 46 secured to posts 48 which are supported in sockets 50 attached to a transversely disposed plate member 52 forming part of a wheel supported carriage assembly which is supported on guide rails carried by frame 1t) below conveyor roller 16. Plate 54 is provided with a hinge connection 56 with plate 46, and plate 54 has associated therewith, Vin the manner described for plate 24, the two-way acting lhydraulic cylinder 58.
The machine, as thus far described, corresponds to the machine which is disclosed in further detail in the aforesaid co-pending application. As disclosed in said application, when a lettuce-filled carton is brought onto the roller conveyor 16, control means are actuated to cause a hydraulic cylinder to move the carriage supporting carton closing assembly 20 inwardly of frame 10 to cause plates 22 and 46 to press against oppositely disposed side walls of the carton, and at the sam-e time the cylinders nection 26 with plate 22, cylindrical post members 28 tfuedly secured to plate 22said post members 28 extend- L to impart clockwise rotation to lever arm 74 and swing4 36 and 58 are actuated to cause the plates 24 and 54 to pivot downwardly and press the closure flaps of the carton to a closed position.
The following elements have been added to the machine to convert it to a machine which will retain all four side Walls of the lettuce-lilled carton against outward bulging when the closure ap presser plates 24 and 54 are moved downwardly. Carton closing assembly 20 is provided with an arm 6l) which upon endward movement of the carriage supporting the assembly is pivoted to press against the end of the carton, as shown in Figure 3, and said assembly is further provided with another arm 62 which upon endward movement of the assembly to the carton engaging position is moved forwardly to be in a position to retain the other end wall of the carton against bulging, as also shown in Figure 3.
The arm 60 is secured to a shaft 64 which is journalled for rotation in sleeve member 66 secured to plate member 52 and within semi-sleeve 68 carried by stub arm 70 which is secured to plate 46. A set collar 72 (see Figure 4) attached to shaft 64 abuts the upper end of sleeve 66 and supports the shaft for rotation. Secured to the lower end of shaft 64 is a lever arm 74 which is pinned toa clevis 76. A second clevis 78 is pinned to a side arm 122 of lever arm 82, and the two clevises 76 and 78 are connected together by a rod 80 having threaded ends of opposite hand. Lever arm 82 is pivotally connected to a fixed arm 84 which is secured to the transverse plate member 52. Lever arm 82 is provided at its free end with a roller 86 which engages a track member 88 having a curved end 90. The track member 83 is secured to frame 10for longitudinal positional adjustment, as by bolts 92 extending through elongated slots, not shown, formed in the track member. Tension springs and 94 interconnect lever arm 82 and clevis 76, respectively, with frame 10.
When a lettuce-lilled carton 96 is moved onto the conveyor 16 between plates 22 and 46 and when plate 46 is caused to be moved toward the carton in the manner described in detail in the aforesaid co-pending application, lever arm 82 is caused to swing in a counterclockwise direction, with reference to Figures 2 and 3, and the roller 86 moves up the curved end 9i) of track member 88,v
thereby causing the clevis aud rod arrangement 76-80 sealed, the springs 92lland 94 cause thearm `6 0 and 1the lever coit'rol'fsystemtherefor to 'move ifr''n'the 'position Figure 3; te the positie a sure 2; rnp a: arm 6o does 'resultare-re vrithrtuereuiorarffom trie veyor ofv'thesealedf'carton; t
