- the differ n f th l ti a t g on the blank 3,603,446 9/1971 Maxey et al 198/33 AB turns it.
- the speeds and axial distance between the in- 3,599,965 8/l97l Humphrey et all 27l/DIG. 7 ard and outward disks may be adjusted to provide various turning results.
- the present invention relates to a carton turner and more specifically to apparatus for turning a carton blank 90 to facilitate feeding the blank into a receptacle in the proper orientation for further processing.
- the apparatus is especially useful, although not limited thereto, in providing a transition between a side seam glueing apparatus and cartoning apparatus.
- side seam glueing apparatus a carton blank is folded and glued along its seam.
- the nature of the side seam gluer is such that the carton blank is fed with its seam extending in a longitudinal direction.
- the nature of the cartoning apparatus is such that the carton blank is fed with the side seam extending in a transverse direction.
- the carton blank from the side seam gluer must be rotated through an angle of 90 and deposited into the magazine of the cartoner with its seam in the transverse direction.
- One objective of my invention has thus been to provide a relatively simple, continuously operating apparatus for turning carton blanks 90 about their centers.
- Another objective of the invention has been to provide a method and apparatus for moving carton blanks along a path in a first orientation and changing the velocity of one side of the carton blank so as to turn the carton blank with respect to the other side of the blank.
- Another objective of the invention has been to provide apparatus including a conveyor and means for feeding carton blanks onto the conveyor with one side of the carton blank projecting laterally beyond the conveyor.
- the portion of the carton blank riding on the conveyor can be held to conveyor speed and the portion projecting beyond the conveyor can be positively gripped to reduce or increase its speed with respect to that of the conveyor, thereby effecting the rotation of the blank.
- my invention includes a conveyor for transporting carton blanks and means for turning the blanks.
- the turning means includes means forming two nips for engaging and turning the blank.
- An inward disk is mounted on a shaft above the conveyor and is freewheeling with respect to the shaft in order to form a first blank engaging nip with the conveyor.
- An outward disk is secured to the shaft and forms a second blank engaging nip with a third disk freely mounted beneath the outward disk on a shaft which drives an end roll of the conveyor.
- the outward disk is driven at a speed greater than that attained by the inward disk by virtue of its engagement with the conveyor or a moving carton thereon.
- Another objective of the invention has been to provide for the adjustability of the turning relationship so as to accommodate the apparatus for changed conditions, including different sizes of cartons.
- the two major parameters which can be changed are the speed of one of the nips and the distance between nips.
- the invention contemplates the adjustment of the latter by simply providing for the axial adjustment of the free-wheeling disk overlying the conveyor.
- the speeds of the conveyor and the inward diskand the speed of the outward disk or the axial distance .between the disks may be adjusted so as to cause a variation in the turning result obtained.
- my invention has the advantage of providing a relatively simple, yet highly reliable, turning apparatus for carton blanks.
- a further advantage is that it is continuously operable to act on a successive number of blanks without the necessity of critical timing or sensing apparatus or the like.
- FIG. I is a perspective view of the invention showing the conveyor, the carton blanks, the disks and a receiv' ing magazine,
- FIG. 2 is a top view of the apparatus showing a blank in a partially turned position
- FIG. 3 is a side view of the invention also showing a blank in a partially turned position, and with the disk driving chain and sprocket removed.
- a conveyor for transporting carton blanks includes a belt 14 which is supported by a typical belt conveyor end roll 15. Upstream of the belt are means 12 for feeding the blanks onto the belt in a longitudinal orientation with a side edge portion 13 projecting laterally beyond said belt.
- the belt 14 is driven in the direction of arrow A" by the roll 15 which is rotated by a conveyor drive shaft 16.
- a chain 17 and sprocket 18 are utilized to connect the drive shaft 16 to a motor (not shown).
- the blanks are positioned on the conveyor belt such that an outward portion 13 extends past the edge of the belt as shown in FIGS. 1 and 2 in order that the blank may be engaged by a nip as will be described.
- the first nip 19 is formed by a free-wheeling idler disk 21 mounted on a shaft 22 above the belt 14. Disk 21. is mounted on shaft 22 so as to permit axial adjustment.
- the shaft 22 is generally parallel to the shaft 16.
- the circumferential surface 27 of the disk 21 is provided with a rubber tire or a coating of like material and the disk is mounted closely enough to the belt 14 to form the nip 19.
- nip 19 engages an inward portion of the carton blanks
- the second nip 20 includes a free-wheeling idler disk 23, which is freely mounted on the conveyor drive shaft 16, and a driven disk 24 which is also provided with a rubber tire or a coating of like material.
- the disk 24 is secured on shaft 22 and is driven thereby.
- the shaft 22 is rotated by a motor (not shown) through chain 25 and sprocket 26 at an angular velocity which provides a peripheral speed of disk 24 which is substantially greater than that of belt 14.
- nip 20 is formed by the cooperation of disks 23 and 24.
- the disk 23 is located outwardly of the conveyor belt 14 and moves independently of it.
- a magazine or receptacle such as that shown at is provided to receive the turned blanks and to feed them to further apparatus such as a cartoner.
- carton blanks are fed onto the belt 14 from the compression section of a side seam gluer, for instance.
- the blanks are generally longitudinally disposed on the belt and are conveyed by it in the direction of arrow A" toward the nips 19 and 20.
- This difference in velocities of two portions of the same blank tends to turn the blank about the nip 19 in the direction of arrow B" in FIG. 2.
- the turning angle may be adjusted'by axial movement of disk 21 to change the distance between its nip l9 and nip 20.
- This velocity of the driven disk 24 may be regulated; however, beneficial results have been obtained when it is 40 to percent greater than that of the conveyor belt 14 and disk 21.
- FIGS. -2 and 3 show a blank 13 in a partially turned position. As disk 24 continues to drive the outward portion 13 of the blank, the blank is further turned and discharged into the magazine 30 in a transverse position which is turned from the previous longitudinal position of the blank.
- My invention offers a very inexpensive solution to the problem or necessity of reorienting carton blanks between different apparatus in an assembly line wherein each apparatus will acceptthe blanks only in respective dissimilar positions.
- a further advantage of my invention is that it operates continuously regardless of the spacing of the blanks on the conveyor and does not require the utilization of any sensing device of elements which move intermittently to engage and turn the blanks.
- Apparatus for turning substantially flat and rigid work pieces through an angle of approximately 90 comprising:
- a blank transporting conveyor means operable at a first velocity to transport said blank in a predetermined direction
- said means forming said first blank engaging nip comprising said conveyor and a first idler disk cooperating with said conveyor
