Definitions

  • a machine which utilizes a suction gripper to remove a lowermost blank in a stack of blanks disposed within a hopper, the blank being moved rearwardly to a position free of a forward lip of the hopper, the blank then being moved forwardly and being placed between
  • This invention relates in general to new and useful irn provements in package forming machines, and more particularly to a machine which is particularly adapted for wrapping a carton blank around a plurality of containers wherein the resultant carton and the containers form together a readily carriable package.
  • containers In the usual package forming machine of the type to which this invention relates, containers, primarily cans and bottles, are fed in two rows with the containers in transverse alignment. A blank is then fed into overlying relation with respect to a predetermined number of the containers, after which the blank is folded around the containers and secured together therebeneath with the containers being interlocked with the carton.
  • Previous machines have several deficiencies. These include the problem of feeding carton blanks in unison with the movement of the containers to assure the proper alignment of the carton blanks with the containers.
  • the double seams or chimes of longitudinally adjacent cans in the rows have a tendency to ride up upon one another so that the cans are not properly positioned for being received within the carton, It is the primary object of this invention to overcome these deficiencies.
  • spring type hold down members are preferably curved by a center divider strip between the two rows of cans and are of a laminated construction whereby the thickness and stiffness of the hold down members gradually decrease as the cans are being brought back into proper alignment.
  • Another object of this invention is to provide suitable hold down members for preventing the riding up of seams or chimes of adjacent cans in rows, the hold down members being of a construction whereby they may be positioned between cans and mechanism for feeding carton blanks into overlying engagement with the cans so that the hold down members in no way interfere with the process of applying cartons to the cans.
  • Another object of this invention is to provide a novel carton blank feed mechanism which is suitable for removing carton blanks from a hopper, the feed mechanism including an upstanding support which is carried by a generally horizontal swing arm which is mounted for vertical oscillatory movement, the support being pivotally connected to the swing arm for swinging about a horizontal axis and having the lower end thereof associated with a suitable guide structure to effect the rocking of the support as it is swung by the swing arm, and the support carrying suitable carton blank gripping means at the upper end thereof.
  • a further object of this invention is to provide a novel carton feed and applying unit which includes a transverse rotating shaft, a frame pivotally mounted on the shaft in overlying relation to the path of containers, the frame having remote from the shaft a feed roll which cooperates with an idler feed roll, a drive mechanism driving the feed roll from the rotating shaft, the drive mechanism including an endless chain having carton blank pushers carried thereby to assure the uniform positioning and movement of carton blanks, the rotating shaft also supporting a carton blank hold down and folding mechanism to initiate the application of a carton blank to a plurality of containers and forming an interlock between the carton blank and the containers whereby the feeding of the carton blank also results in the feeding of the containers.
  • Yet another object of this invention is to provide a novel take away conveyor structure which is specifically configurated for engaging both a carton and containers disposed therein and for exerting a pressure on the carton and containers to effect the movement thereof away from the package forming machine.
  • FIGURE 1 is a plan view of a package forming machine in accordance with this invention, only the specific details of those features of the machine which are parts of this invention being fully illustrated.
  • FIGURE 2 is an enlarged fragmentary longitudinal vertical sectional view taken along the line 2--2 of FIGURE 1 and shows more specifically the details of the carton blank feeding and applying mechanism.
  • FIGURE 3 is an enlarged fragmentary horizontal sectional view of the machine in the vicinity of the carton blank hopper and shows the specific details of construction of the hopper.
  • FIGURE 4 is an enlarged fragmentary transverse vertical sectional view taken along the line 4-4 of FIGURE 3 and shows the specific manner in which cans are fed along a predetermined path in two rows.
  • FIGURE 5 is a schematic longitudinal vertical view showing the drive mechanism for the various components of the machine which are believed to be novel.
  • FIGURES 6', 7 and 8 are schematic longitudinal elevational views showing steps in the sequence of removing a carton blank from a hopper and transferring the carton blank to feed rolls.
  • FIGURE 9 is an enlarged fragmentary longitudinal sectional view taken generally through the center of the machine and shows the specific manner in which carton blanks are delivered to a plurality of cans and the manner in which the spacing of the carton blanks is maintained.
  • FIGURE is an enlarged fragmentary longitudinal vertical sectional view showing the manner in which the spring hold down is carried by the central divider.
  • FIGURE 11 is an enlarged fragmentary side elevational view showing the manner in which the take away conveyor engages both the carton and a can of a completed package.
  • FIGURE 12 is an enlarged fragmentary side elevational view of a modified form of machine particularly adapted for forming packages wherein. the containers are in the form of bottles.
  • containers. to be packaged are fed into the machine in two rows disposed in closely spaced, but definitely separated, relation. Transversely adjacent containers are then brought into alignment and fed in unison through the machine. With the containers being properly fed at a predetermined rate, a carton blank is provided and is positioned in overlying relation to the containers. When the containers are in the form of bottles, the carton blank is provided with openings for the necks of the bottles and the central part of the carton blank is merely slipped over the necks of the bottles. This solves the problem of alignment.
  • FIGURE 3 in particular wherein there is illustrated a carton blank, generally referred to by the numeral for which the machine of this invention is particularly adapted although the machine may be slightly modified to utilize other carton blanks.
  • the carton blank 20 generally corresponds to the carton blank shown in Patent No. 2,986,857 and differs therefrom primarily in the scalloped edge configuration thereof. It is to be noted that the carton blank 20 includes a centrally located top panel 21, a pair of next adjacent side panels 22 and a pair of outer bottom forming panels 23 and 24.
  • the bottom forming panels 23 and 24 are provided with interlocking means of the type broadly shown and described in Patent No. 2,988,857. Further description is believed to be unnecessary here in that this invention has nothing to do with the manner in which the bottom forming panels 23 and 24 are interlocked.
