Description
- The present invention relates to a packaging machine including a bottom folding device for containers such as cartons for containing milk.
- As disclosed, for example, in the document US-A-4,776,830, such packaging machines comprise a rotor having a mandrel wheel provided by radial mandrels which are successively stoppable at a folding station, a folding device operable on a container fitted around the mandrel as stopped at the folding station for folding an end portion of the container to form the bottom thereof, and a pressure member for holding the container against an axial force exerted on the container by the folding operation of the folding device. The folding operation of the folding device and the pressing operation of the pressure member are effected respectively by two hydraulic cylinders which are operated in synchronism.
- The known machine described requires a control device for synchromizing the two hydraulic cylinders and is therefore complex.
- The main object of the present invention is to provide a packaging machine having a simple construction and comprising a folding device and a pressure member which can be operated in synchronism by a single drive source.
- The present invention provides a packaging machine which comprises a rotor having a mandrel wheel provided by radial mandrels, the mandrels being successively stoppable at a folding station, a folding device operable on a container fitted around the mandrel as stopped at the folding station for folding an end portion of the container to form the bottom thereof, and a pressure member for holding the container against an axial force exerted on the container by the folding operation of the folding device. The packaging machine is characterized in that the pressure member is biased by a spring so that an operation of the folding device before starting the folding operation permits the pressure member to press the container against the mandrel, the container being releasable from the pressure member against the spring by an operation of the folding device subsequent to the folding operation thereof.
- With the packaging machine of the present invention, the pressure member is biased by a spring so that an operation of the folding device before starting the folding operation permits the pressure member to press the container against the mandrel, and the container is relieved of the pressure of the pressure member against the spring by an operation of the folding device after the folding operation. Accordingly, the present machine requires no hydraulic cylinder for operating the pressure member unlike the conventional machine described first.
- Consequently, the folding device and the pressure member are operable in synchronism by a single drive source. The packaging machine provided by the invention is therefore simplified in construction.

drivable rotor 22 having eightradial mandrels 21 so arranged as to stop at first to eighth eight processing stations I to VIII successively, acontainer feeder 23 disposed at the first processing station I, abottom heater 24 disposed at the fourth processing station IV, abottom folding device 25 at the fifth processing station V, a bottomcompression bonding device 26 at the sixth station VI, acontainer discharge device 27 at the eighth processing station VIII and acontainer transport conveyor 28 extending from the eighth processing station VIII as the starting end of its transport path. - The second processing station II, third processing station III and seventh processing station VII are all supplementary stations.
- With reference to FIGS. 2 to 6, the
bottom folding device 25 comprises ayoke 30 disposed outwardly of and in alignment with themandrel 21 as stopped at the fifth processing station V, a pair offirst folding members 31 mounted on theyoke 30 and openable in the direction of movement of the mandrel, a pair ofsecond folding members 32 mounted on theyoke 30 and openable in a direction orthogonal to the direction of movement of the mandrel, and apressure member 33 for pressing thecontainer 11 against themandrel 21 before the first foldingmembers 31 perform a folding operation. - The
yoke 30 is in the form of a box which is open inward, and is fixedly connected to the bottomcompression bonding device 26 by abracket 34. Thebonding device 26 is supported by a machine frame. A pair ofinner support shafts 35 extending in parallel to each other in a direction orthogonal to the direction of movement of the mandrel are rotatably mounted on theyoke 30 at its inner end.

first folding members 31 comprises a dependingplate 41 fixed at its upper end to theinner support shaft 35 and atriangular plate 42 secured to the lower end of the dependingplate 41. When combined together, the pair oftriangulare plates 42 are in an inverted V-shape in vertical section (indicated in broken lines in FIG. 3). - Each of the two

yoke 30 is a horizontalrotary shaft 50 extending in parallel to theinner support shaft 35. Theshaft 50 is supported and driven by unillustrated means. Fixed to therotary shaft 50 are a downwardfirst arm 51 and an upwardsecond arm 52. Thefirst arm 51 has connected thereto one end of afirst rod 53, the other end of which is connected to one of thefirst folding members 31. On the other hand, asecond rod 54 has one end connected to thesecond arm 52 and the other end connected to athird arm 55 secured to one of theouter support shafts 36. - When the
rotary shaft 50 is driven, one of thefirst folding members 31 is pivotally moved through thefirst arm 51 and therod 53, and this movement is transmitted to the otherfirst folding member 31 via theinner support shafts 35 and thegears 37, consequently opening or closing thefirst folding members 31. At the same time, the rotation of therotary shaft 50 is transmitted to one of theouter support shaft 36 by way of thesecond arm 52,second rod 54 andthird arm 55 to cause thegears 38 to rotate theouter support shafts 36 in opposite directions. As a result, the twosecond folding members 32 are opened or closed. - The
pressure member 33 comprises apressure pad 61 facing the path of movement of the mandrel, and aretractable rod 62 extending from thepressure pad 61 in a direction opposite to themandrel 21 and orthogonal to the axis of the mandrel. - With reference to FIGS. 2 and 4, the
rotor 22 has two mandrel wheels. Disposed between twomandrels 21 brought to a halt at the fifth processing station V is aninclined post 63 extending from a rotor bearing in parallel to the mandrels.

Theserods 52 extend in opposite directions in alignment with each other, and are each supported by abearing 65 on theplate 64 so as to project outward beyond thebearing 65. Apusher plate 66 and aspring retainer 67 are secured to each of the opposed ends of the tworetractable rods 62. A coiledcompression spring 68 is provided between the twospring retainers 67, whereby eachpressure member 33 is always biased toward thecorresponding mandrel 21. - When a
container 11 is brought to the fifth processing station V, the first andsecond folding members contact portion 45 of thesecond folding member 32 is in bearing contact with thepusher plate 66, holding thepressure member 33 away from themandrel 21 against thespring 68. - Upon the delivery of the
container 11 to the fifth processing station V, therotary shaft 50 is driven counterclockwise in FIG. 3, and the first andsecond folding members first folding members 31 first fold the first andthird bottom panels container 11 as fitted around themandrel 21 inward along thescores 19. Subsequently, thesecond folding members 32 inwardly fold the second andfourth bottom panels third bottom panels second folding members 32 move from the open position toward the closed positon, thepressure member 33 moves toward themandrel 21 and is pressed against themandrel 21 with thecontainer 11 positioned there-between. The time when the pressure member is thus pressed is before the first foldingmembers 31 perform the folding operation. - Although the
container 11 fitted to themandrel 21 by the folding operation of the first and second foldingmembers container 11 is held to themandrel 21 against movement by being pressed against themandrel 21 by thepressure member 33. - The first and
second folding members rotary shaft 50 is now driven clockwise in FIG. 3. The first andsecond folding members first folding members 31 directly move to the open position, while thesecond folding member 32 comes into contact with thepusher plate 66 of thepressure member 33 in the course of the movement and moves to the closed position while moving theplate 66 away from themandrel 21. - The
rotor 22 is then driven by one pitch, thecontainer 11 with the folded bottom is brought out of the fifth processing station V, thecontainer 11 to be folded next is delivered to the station V, and the machine resumes the initial state to complete one cycle of folding operation.
