Abstract

The disclosure relates to an apparatus for applying objects such as spoons or suction tubes diagonally to a side wall of a packing container. As the containers are advanced by a conveyor, a carriage reciprocates adjacent the conveyor. A rotary drum is mounted on an inclined axle on the carriage. The objects are supplied to the drum in the form of a band in which the objects are spaced apart. The drum holds the individual objects while they are severed from the band by a reciprocating knife. Rotation of drum positions each object in a correct angular position with respect to the side wall of the container. An adhesive applicator is also positioned on the carriage to apply adhesive to the side wall of the container. A transfer arm applies the object against the side wall of the container where it is retained by the adhesive.

Claims

1. Apparatus for the individual application of elongated objects to packing containers, said apparatus comprising a conveyor for advancing the packing containers, driving means for advancing said objects to a predetermined position for transfer to the packing containers, said driving means being supported by a carriage movable along a portion of the conveyor to perform a working stroke synchronously with movement of the conveyor wherein said driving means cooperates with a cutting means and a transfer means so that said objects are applied to said packing containers in a predetermined angular position with respect to said packing container, said driving means, said cutting means and said transfer means being inclined relative to the path of feed of said packing containers, said objects advanced to said driving means along a path extending at the same angle of inclination as the feed path of said packing containers.

2. The apparatus in accordance with claim 1, wherein the driving means is rotatably supported in the carriage and includes a plurality of peripheral recesses for receiving said objects and a guide rail extending along a part of the periphery of the driving means so as to retain the objects in the recesses.

3. The arrangement in accordance with claim 1, wherein said cutting means positioned on said carriage cooperates with said driving means for separating said objects.

4. The apparatus in accordance with claim 3, wherein said cutting means comprises a knife adjacent said driving means and a fixed element extending into a recess in said driving means so that an active part of said element extends between said knife and a center axle of said driving means.

5. The apparatus in accordance with claim 2, wherein said transfer means extends into one of said peripheral recesses in said driving means and is maneuverable between a first position wherein an active part of said transfer means is located between a central axis of the driving means and an object advanced to a selected position for transfer to a packing container and a second position wherein the transfer means applies said coherent object against a wall surface of the packing container.

6. The apparatus in accordance with claim 2, wherein said driving means is rotated in steps, each step occurring when said carriage performs a working stroke.

7. The apparatus in accordance with claim 6, wherein said advance of said packing containers during application of said objects to said packing containers is guided by a feed chain provided with drivers.

8. The apparatus in accordance with claim 3 wherein said objects are supplied to said driving means in a continuous band, said driving means advancing said objects from a second predetermined position to said first mentioned position, said cutting means being located adjacent said driving means for severing individual objects from said band at said second position, and means on said carriage for applying adhesive to the packing containers for subsequent application of said objects to the containers.

9. A method of applying an elongated object diagonally to a side wall of a packing container in a continuous operation including the steps of:

(a) advancing a plurality of packing containers on a conveyor at uniform spaced intervals along a straight feed path;

(b) advancing a band of elongated objects, said objects having their greater dimensions extending transversely of the direction of advance of said band;

(c) severing said objects individually from said band while holding said objects diagonally relative to the side wall of the containers;

(d) advancing said objects to a position adjacent to containers on the conveyor;

(e) applying adhesive to the side wall of the container; and

(f) transferring said one of said objects from a position adjacent the container to the side wall of the container in a predetermined angular position while said container advances along said conveyor wherein the advancing of the packing container, the severing of the objects and the transferring of said one of the objects is along a path inclined relative to said feed path.
