  • the use of a pushing device to provide a supply of packages in a wrapping machine is well known in the prior art. Examples of such wrapping machines are found in U.S. Pat. Nos. 2,373,655 and 3,055,490.
  • a single transverse bar is used in combination with a double endless chain mechanism to move packages from a supply location into a receiving means.
  • the receiving means in each of these prior art patents is a turret wheel assembly used for wrapping packages.
  • the prior art has also disclosed the use of the transverse rod to press one of the flaps of the wrapper sheet against a moistening wick for the purpose of applying an adhesive or moistening material to the wrapper sheet material.
  • This invention relates to a combination comprising engaging means for contacting the following side of at least one package being fed into a wrapping machine.
  • the engaging means includes a primary pushing means and an auxiliary pushing means.
  • the auxiliary pushing means is disposed directly behind the primary pushing means and moves in the same line of travel as the package being fed into the wrapping machine.
  • the engaging means and package are moved along a path to a wrapper sheet applying station.
  • a means is provided for receiving the package after a wrapper sheet has been applied thereto.
  • the receiving means consists of a turret wheel assembly having a plurality of pockets for receiving the packages.
  • Transverse rod members are used in a specific embodiment of this invention to constitute the primary pushing means and the auxiliary pushing means.
  • the first rod urges the package into the turret wheel assembly and the auxiliary pushing rod is effective to insure a firm seating of the package in place within each turret wheel pocket which receives a package.
  • a stationary liquid-applying device is disposed immediately below the turret wheel assembly.
  • the wrapper sheet is disposed across the advanced end and two sides of the package with both ends of the wrapper-sheet-projecting rearwardly from the turret wheel pocket.
  • the first pusher member acts to press one of the rearwardly projecting ends of the wrapper sheet against the liquid-applying device.
  • the second pusher rod provides a supplementary pressing action between the wrapper-sheet-projecting end and the liquid-applying device.
  • auxiliary pushing means which is a second transverse pusher member in these specific embodiments, the disadvantages associated with the use of a single pusher rod member are clearly overcome.
  • FIG. 1 is a top plan view of a double pusher assembly made in accordance with this invention
  • FIG. 2 is a partial cross-sectional view of the double pusher assembly urging a package along a horizontal support
  • FIG. 3 is a partial cross-sectional view of a pusher assembly of FIG. 1 shown urging a package into a receiving means;
  • FIG. 4 is the pusher assembly of FIG. 1 shown at an advanced stage of operation
  • FIG. 5 is a partial sectional view of the assembly of FIG. 1 showing the action of the auxiliary pushing means on the package
  • FIG. 6 is a partial cross-sectional view of the assembly of FIG. 1 showing the action of the auxiliary pushing means in combination with a liquid applying device.
  • a pushing assembly generally designated I0, includes a pair of endless chains 11 and a plurality of transverse pusher members 12 and 13.
  • the pusher members 12 and 13 are fixedly attached to the chains 11.
  • the primary pusher member 12 engages the following side of the package 14.
  • the auxiliary pushing member 13 is disposed oehind the primary pusher member 12.
  • the wrapper-sheet-applying station is not shown in the instant case and does not form a part of this invention. Any conventional manner of applying a wrapper sheet onto a package may be used in combination with the pusher assembly 10.
  • a mechanism for feeding and cutting wrapper sheets to be placed over packages is shown in U.S. Pat. No. 2,837,978.
  • the package 14 moves along the support 15 while being urged to the wrapper-sheet-applying station.
  • the endless chains 11 move along a channel 16.
  • the manner in which the endless chains 11 move through the mechanism is another conventional structure heretofore known in the prior art.
  • the wrapper sheet material may be cellophane or any other film material.
  • Each of the endless chain 11 engage sprockets 17 which are laterally spaced with respect to each other and located adjacent a wrapping machine receiving means.
  • the receiving means in this specific embodiment constitutes a turret wheel assembly 18.
  • the turret wheel assembly 18 has a plurality of radial pockets as is well known in the prior art. See in particular US. Pat. Nos. 3,055,490 and 2,373,655.
  • the chain 11 which is used to push packages into the turret wheel assembly 18 is constantly driven.
  • the speed of the turret wheel assembly 18 is correlated with the speed of the chain drive 11. This operation involves synchronization to effect the desired packaging.
  • Each pocket is formed by the pocket members 19 and 20 which support the package 14 within the turret wheel assembly 18.
  • the primary pusher member 12 is effective to urge the package 14 into the receiving means constituted by the pocket members 19 and 20.
  • the auxiliary pusher member 13 is allowed to contact the package 14. In this way, pusher member 13 is effective to insure a firm seating of the package 14 in place within the pocket of the turret wheel assembly 18.
  • the pocket members 19 and 20 engage the package 14 adjacent one end thereof. Similar pocket members engage the package 14 at the other end thereof.
  • a folding platform 21 is disposed between the sets of pocket members forming each pocket in the turret wheel assembly 18. The stationary platform member 21 is fixedly mounted onto the wrapping machine with the frame structure 21a.
  • a stationary liquid-applying device 24 is disposed adjacent the receiving means in this specific embodiment.
  • the stationary liquid-applying device 24 includes a vertically disposed working member 25 which is moistened with either a solvent liquid or an adhesive material.
  • a solvent liquid or an adhesive material As the conveyor chains 11 change the direction of travel of the primary pushing member 12 and auxiliary pushing member 13, each pusher member 12 and 13 comes into successive contact with the lower projecting end 23 of the wrapper sheet which has been placed around the package 14.
  • the auxiliary pushing member 13 becomes effective to insure an additional thorough application of liquid from the liquid-applying wick 25.
  • the stationary platform 21 provides a place against which the auxiliary pushing member 13 folds the projecting end 23 of the wrapper sheet.
  • the endless chains -ill continue to move around the axially aligned and laterally spaced sprockets 17, the auxiliary pusher member 13 exerts an additional force onto the projecting end against the wick 25.
  • This action insures fulland complete application of either a solvent material or an adhesive material to the end 23 for subsequent joining of the ends 22 and 23 around the following end of the package 14.
  • the step-by-step operation of the pushing assembly 10 made in accordance with this invention is sequentially shown in FIGS. 3 through 6.
  • engaging means may be used to contact the following side of at least one package moving into a wrapping machine.
  • a primary pushing means and an auxiliary pushing means disposed therebehind the desired effects as outlined in the above description may be obtained.
  • Any desired means may be used for moving the engaging means and the package along a path to a wrapper-sheet-applying station. It is not absolutely necessary that the engaging means and the conveying means for the package are a part of the same structure. However, the two structures are clearly used in combination as set forth in the above-described specific embodiments.
  • a very important aspect of this invention is directed to the changing of the direction of travel for the primary pushing means to thereby allow the auxiliary pushing means to engage the following side of the package 14.
  • auxiliary pushing means effects the additional thorough application of liquid from the liquid-applying device
  • the structure of the liquid-applying device 24 is deemed to be well known in the prior art and does not form a part of this invention.
  • a specific type of device which may be incorporated in the structure of the combination as disclosed herein may be found in US. Pat. 2,373,655.
