Abstract
Description
- The present invention relates to packaging machines for preparing containers having a top in the form of a gabled roof with a top rib, and more particularly to an apparatus for use in the machine for bonding with pressure the top portions of each container to be folded into the gabled roof.
- Apparatus of this type are already known which comprise a pair of pressure members arranged on opposite sides of a path of transport of containers formed by a conveyor.
- FIG. 7 shows a
container 11 having top portions to be joined together by bonding with application of pressure (hereinafter referred to merely as "bonding"). Thecontainer 11 has atrunk 12 having a square horizontal cross section, a closedbottom 13 formed by folding the lower end of the trunk flat, and atop 14. Thetop 14 of the container to be formed into a gabled roof comprises a pair ofouter top panels 15, and a pair ofinner top panels 16 foldable inward between the pair ofouter top panels 15. Arib 19 is formed by a pair ofouter rib panels 17 extending from the upper ends of the respectiveouter top panels 15, and a pair ofinner rib panels 18 extending from the upper ends of the respectiveinner top panels 16 and foldable in two and holdable between theouter rib panels 17. The container is made of a paper-base laminate (not shown) having a thermoplastic synthetic resin film coating on the inner and outer surfaces thereof. - FIG. 8 shows the
container 11 as bonded at itstop rib 19 improperly by the above apparatus. More specifically, therib panels rib 19 are bonded out of register. - The cause of this faulty bonding is as follows. FIG. 9 shows the
container 11 and a holder H therefor. The holder H comprises four vertical pieces L-shaped in cross section and extending along the respective four corners of the container externally thereof. The two pairs of vertical pieces are attached to a pair of opposed horizontal endless chains L, respectively. If the chain L becomes stretched or if the vertical piece is attached as improperly adjusted in position, the two pairs will become displaced from each other longitudinally of the chains L. - The container held by the vertical pieces thus displaced deforms to a slightly flattened rhombic form from a square indicated in a broken line when seen from above, with the
rib panels rib 19 positioned out of register in the longitudinal direction. If thecontainer top 14 is bonded in this state, a faulty joint will result as seen in FIG. 8. - The main object of the present invention is to provide an apparatus for bonding top portions of containers without producing such faulty joints.
- The present invention provides an apparatus for bonding top portions of containers with pressure which comprises a pair of pressure members disposed at opposite sides of a path of travel of container tops and movable outward and away from each other, and a pair of correcting members movable with the respective pressure members toward and away from each other and adapted to act on required portions of the container before the pressure members are moved toward each other to correct the position of the outer rib panels and the inner rib panels.
- When these rib panels for forming a rib are out of register, the correcting members of the bonding apparatus of the invention eliminate the misregister.
- Accordingly, the outer and inner rib panels are bonded in register by the pressure members. Thus, the invention obviates faulty bonding due to misregister of the rib panels.
