Definitions
- the present invention relates to a device for erecting flat folded carton sleeves into cartons.
- Packaging of various articles requires erecting flat folded carton sleeves which will form packages.
- the sleeves are usually supplied in flat folded configuration and are stacked in suitable magazines of the packaging machine.
- Various devices for erecting flat folded carton sleeves have heretofore been provided. These devices include e.g. means for taking over sleeves to be erected, like suction means and similar, carried by lever systems which move the taking over means from a position in which a sleeve to be erected is withdrawn from the magazine, to a position in which the already erected sleeve is placed on the conveying line of the packaging machine.
- the sleeve is erected either by other gripping means which grip the sleeve on the surface opposite to the one acted upon to withdraw the sleeve, and are operated to move with respect to the taking over means, or by stationary abutment means which strike the withdrawn sleeve during the transferring to the conveying line.
- the means used for erecting flat folded carton sleeves are usually complicated and often rather big.
- the EP-A-440940 discloses a device for removing carton sleeves from a magazine, in which the carton sleeves are stored in a stack, and for unfolding the carton sleeve during transferring to a conveying line.
- the carton sleeves are taken away by a rotating drum and to unfold the sleeve, there is an oscillating arm hinged to the rotating drum and driven by cam means. This way, an open ended boxes are obtained due to rotation of the drum.
- the device does not includes a series of arms hinged to each other and acting to remove and unfold the carton sleeves.
- the present invention was evolved with the general object of providing a device for simple erecting flat folded carton sleeves during their transfer from the relative magazine to a conveying line for subsequent packaging steps.
- Another object of the present invention is to propose a device for erecting flat folded carton sleeves, which is simple, versatile and has limited dimensions.
- Reference numeral 1 generally designates a device for erecting flat folded carton sleeves 2.
- Flat folded carton sleeves 2 to be erected are stacked inside a magazine 3, open at the bottom and preferably inclined.
- the device 1 includes a lever mechanism 10, which features a first arm 11 and a second arm 12, each one pivoted at one end to a stationary frame, about a common axis of a first horizontal pin 13.
- the arms 11, 12 are driven into oscillation within parallel vertical planes by independent driving means, e.g. cams or the like, which are not shown.
- the free end of the first arm 11 supports a first connecting rod 14, which is hinged thereto by a second horizontal pin 16.

- the first connecting rod 14 carries, integral therewith, a taking over member 19, suitably squared shaped and extending within the same vertical plane in which the first connecting rod oscillates.
- the taking over member 19 carries on its free end withdrawing suction cups 20, which are connected to suction means for withdrawing the lowermost sleeve 2 from the magazine 3.
- the device 1 includes also a folding mechanism 30 featuring a third arm 31, which is pivoted to the stationary frame on a fifth pin 32 having a horizontal axis. Therefore, the third arm 31 oscillates within a vertical plane, parallel to the oscillation plane of the first and second arms 11, 12.
- a third connecting rod 34 is hinged at one end to the third arm 31 by means of a sixth pin 33, and at the other end to the taking over member 19 by means of a seventh pin 35.

- the first arm 11 is imparted a rotation, so as to withdraw the carton sleeve 2 from the magazine 3.
- the rotation of the first arm 11 determines an inverse rotation of the first connecting rod 14, and consequently, inclination of the taking over member 19, on which the carton sleeve 2 is kept ( Figure 2).
- first arm 11 and the second arm 12 are imparted rotations in the same direction and with equal amplitudes, which allows the first connecting rod 14, carrying the carton sleeve 2 on the taking over member 19, to continue its rotation (Figure 3).
- the rotation of the first connecting rod 14 drives to move the third connecting rod 34, which has the folding member 36 joined thereto.
- the folding member 36 acts on the wall of the carton sleeve 2 adjacent to its wall kept by the suction cups 20, thus erecting the sleeve.
- the first arm 11 and the second arm 12 continue to rotate in the same direction, but the rotation amplitude of the first arm 11 is bigger until the angle defined by the reciprocal positions of the arms reaches the maximum amplitude, so that the sleeve 2 is introduced between the opposite belts 41, 42 of a conveying line 4, which moves in a continuous or intermittent way ( Figure 4).
- the folding member 36 folds the sleeve 2 by an angle slightly bigger than the final one, so as to yield it to such an extent as to prevent the material elastic return.
- the device returns to the position for withdrawing and erecting a subsequent flat folded carton sleeve.
- the proposed device fulfils the object of simple erecting flat folded carton sleeves.
- flat folded carton sleeves are erected during their transfer from the magazine to a line conveying erected sleeves for subsequent packaging steps.
- the proposed device is small and does not feature stationary abutment elements and the like.
- Another advantage of the present invention derives from the fact that it allows an easy change over when the size of flat folded carton sleeves to be erected is changed, without complicated adjustment operations.

Description
- The present invention relates to a device for erecting flat folded carton sleeves into cartons.
- Packaging of various articles requires erecting flat folded carton sleeves which will form packages.
- The sleeves are usually supplied in flat folded configuration and are stacked in suitable magazines of the packaging machine.
- Various devices for erecting flat folded carton sleeves have heretofore been provided. These devices include e.g. means for taking over sleeves to be erected, like suction means and similar, carried by lever systems which move the taking over means from a position in which a sleeve to be erected is withdrawn from the magazine, to a position in which the already erected sleeve is placed on the conveying line of the packaging machine.
- The sleeve is erected either by other gripping means which grip the sleeve on the surface opposite to the one acted upon to withdraw the sleeve, and are operated to move with respect to the taking over means, or by stationary abutment means which strike the withdrawn sleeve during the transferring to the conveying line.
- The means used for erecting flat folded carton sleeves are usually complicated and often rather big.
- In fact, a special working station is needed for erecting flat folded carton sleeves.
- The EP-A-440940 discloses a device for removing carton sleeves from a magazine, in which the carton sleeves are stored in a stack, and for unfolding the carton sleeve during transferring to a conveying line. The carton sleeves are taken away by a rotating drum and to unfold the sleeve, there is an oscillating arm hinged to the rotating drum and driven by cam means. This way, an open ended boxes are obtained due to rotation of the drum. The device does not includes a series of arms hinged to each other and acting to remove and unfold the carton sleeves.
- The present invention was evolved with the general object of providing a device for simple erecting flat folded carton sleeves during their transfer from the relative magazine to a conveying line for subsequent packaging steps.
- Another object of the present invention is to propose a device for erecting flat folded carton sleeves, which is simple, versatile and has limited dimensions.
- The above mentioned objects are obtained in accordance with the contents of the claims.
- The characteristic features of the present invention will become more fully apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:
- Figure 1 is a schematic lateral view of the proposed device during withdrawing of a flat folded carton sleeve;
- Figures 2, 3 and 4 are lateral views of the proposed device, during subsequent working steps.
- Reference numeral 1 generally designates a device for erecting flat folded
carton sleeves 2. - Flat folded
carton sleeves 2 to be erected are stacked inside amagazine 3, open at the bottom and preferably inclined. - The device 1 includes a
lever mechanism 10, which features afirst arm 11 and asecond arm 12, each one pivoted at one end to a stationary frame, about a common axis of a firsthorizontal pin 13. - The
arms - The free end of the
first arm 11 supports a first connectingrod 14, which is hinged thereto by a secondhorizontal pin 16. - Likewise, the free end of the
second arm 12 supports a second connectingrod 15, hinged thereto by a thirdhorizontal pin 17. - The connecting
rods arms fourth pin 18. - The first connecting
rod 14 carries, integral therewith, a taking overmember 19, suitably squared shaped and extending within the same vertical plane in which the first connecting rod oscillates. - The taking over
member 19 carries on its free end withdrawingsuction cups 20, which are connected to suction means for withdrawing thelowermost sleeve 2 from themagazine 3. - The device 1 includes also a
folding mechanism 30 featuring athird arm 31, which is pivoted to the stationary frame on afifth pin 32 having a horizontal axis. Therefore, thethird arm 31 oscillates within a vertical plane, parallel to the oscillation plane of the first andsecond arms - A third connecting
rod 34 is hinged at one end to thethird arm 31 by means of asixth pin 33, and at the other end to the taking overmember 19 by means of aseventh pin 35. - A folding
member 36 is joined to the third connectingrod 34 at a suitable angle with respect to the longitudinal axis thereof. - Operation of the device will be now described beginning from the withdrawing of a flat folded
carton sleeve 2 from themagazine 3. - During the withdrawing, the taking over
member 19 carrying thesuction cups 20 is brought to a position, in which it is substantially perpendicular to the bottom of themagazine 3, so that thelowermost carton sleeve 2 goes in abutment against the suction cups 20 (Figure 1). - It is to be noted that this withdrawing position of the
suction cups 20 is determined by the reciprocal positions of thefirst arm 11 and thesecond arm 12. Although thefirst arm 11 and thesecond arm 12 are operated independently, they are moved in time relation and are linked to each other by the respective first and second connectingrod fourth pin 18. - In fact, the taking over
member 19 carrying thesuction cups 20 is an extension of the first connectingrod 14. - The
first arm 11 is imparted a rotation, so as to withdraw thecarton sleeve 2 from themagazine 3. - With the
second arm 12 being motionless, the rotation of thefirst arm 11 determines an inverse rotation of the first connectingrod 14, and consequently, inclination of the taking overmember 19, on which thecarton sleeve 2 is kept (Figure 2). - Subsequently, the
first arm 11 and thesecond arm 12 are imparted rotations in the same direction and with equal amplitudes, which allows the first connectingrod 14, carrying thecarton sleeve 2 on the taking overmember 19, to continue its rotation (Figure 3). - The rotation of the first connecting
rod 14 drives to move the third connectingrod 34, which has the foldingmember 36 joined thereto. - The folding
member 36 acts on the wall of thecarton sleeve 2 adjacent to its wall kept by thesuction cups 20, thus erecting the sleeve. - The
first arm 11 and thesecond arm 12 continue to rotate in the same direction, but the rotation amplitude of thefirst arm 11 is bigger until the angle defined by the reciprocal positions of the arms reaches the maximum amplitude, so that thesleeve 2 is introduced between theopposite belts conveying line 4, which moves in a continuous or intermittent way (Figure 4). - It is to be noted that when the
sleeve 2 is introduced between thebelts folding member 36 folds thesleeve 2 by an angle slightly bigger than the final one, so as to yield it to such an extent as to prevent the material elastic return. - Then, the device returns to the position for withdrawing and erecting a subsequent flat folded carton sleeve.
- Thus, the proposed device fulfils the object of simple erecting flat folded carton sleeves.
- It is to be noted that flat folded carton sleeves are erected during their transfer from the magazine to a line conveying erected sleeves for subsequent packaging steps.
- Moreover, the proposed device is small and does not feature stationary abutment elements and the like.
- Another advantage of the present invention derives from the fact that it allows an easy change over when the size of flat folded carton sleeves to be erected is changed, without complicated adjustment operations.
