Definitions

  • the invention is directed to an apparatus for assembling thin-walled container halves.
  • a container is formed of thick-walled cylinder halves, one of which is necked out and the second necked in, the second half being telescoped into the first and the halve are then welded together.
  • This may be effective for thick-walled containers which retain their shape after reforming, but thin-walled containers, particularly if made from relatively soft metal such as aluminum, are very unstable in retaining their shape and thus are difficult to assemble and in forming the edges, are hard to control. This is especially significant for high-speed production of 400-1000 units per minute.
  • the object of this invention is to provide a novel apparatus for assembling the container halves which overcome the foregoing problems.
  • the present invention provides an apparatus for assembling a pair of thin-walled cup-shaped container sections adapted to be assembled end to end and each section comprising a cylindrical body wall having an open end defined by an end portion of the body wall which normally assumes an out of round shape; comprising a support; means for mounting said sections in axially spaced aligned relation and the end portion of each opposing the other; a die assembly mounted on the support in a position to receive one of the container sections at one side thereof and the other container section at the opposite side thereof; said die assembly comprising an opening there through; outer guide means at opposite sides thereof for guiding the end portions of respective container sections into said opening; said opening being defined at one side of the die assembly by a cylindrical surface disposed inwardly as said guide means as a continuation thereof and of a diameter to snugly engage the external side of a container section insertable therein to shape and hold the same round; said guide means on the other side of said guide assembly extending through said shoulder and defining an inner edge thereof; said shoulder having a radial extent
  • the first and second container halves are advanced toward each other at opposite sides of the die and the second half is forced through the necking surface and is slightly necked in while the first half is disposed in receiving position.
  • the second half is being necked in, it also wedges into the first half.
  • the outer container is held round (squared) in the die assembly.
  • the entering portion of the inner container is slightly necked in while relatively advancing the two halves toward each other and while holding them under control so that the inner container portion easily enters the open end of the outer portion.
  • the inner portion is under compression and after release from the die, springs outwardly and produces a hoop tension in the outer portion.
  • the adhesive preferably is a vinyl plastisol material which solidifies on being heated after the container sections are mated.
  • the container sections are released when telescoped and the inner section expands and compresses the trapped adhesive and thus maintains intimate pressed contact between the parts so that they adequately bond with the adhesive as it cures or sets.
  • Suitable adhesive materials for bonding the two container sections together can be any known materials having adhesive properties including vinyl plastisols, thermosetting epoxy resins and thermoplastic resins such as polyethylene, polypropylene.
  • Other adhesive materials include vinyl plastisol formulations, carboxylated polyolefin resins and especially carboxylrted polypropylene resins of the type disclosed in U.S. Patent 3,616,047.
  • the apparatus 31 comprises a support frame 32 which has a plurality of vertically aligned bearings 33 and 34 mounted thereon in which an operating shaft assembly 35 is journaled.
  • the shaft assembly is split into two counter- rotary sections 38 and 40.
  • Shaft section 38 is connected to one jaw or clamp holder 42 and the shaft section 40 is connected to jaw or clamp holder 44 of a die 45.
  • the jaw sections each carry a half section segment 46 of a die ring 47.
  • Each section 46 has a tongue 48 fitted into a groove 50, in the associated jaw or clamp holder 42 or 44.
  • an end stop 52 at each end of segment 46 abutting the end of the same, the stop being attached by screws 54, 54 threaded into the associated end portion of the jaw section 42 or 14.
  • Jaws 42, 44 have arms 55, 56 respectively at one of their ends keyed by keys 57, 58 to the respective shaft sections 38 and 40.
  • the shaft sections 38 and 40 are connected to pistons 64, 66 of air or hydraulic motors 68, 70, the pistons operating in cylinders 72, 74.
  • cup-shaped container halves or cups 75, 76 which are made of metal, preferably aluminum of about 6-10 mils in thickness.
  • Associated delivery and discharge mechanism is used to bring the cups to the assembly apparatus 31 and to remove the assembled container but are of no concern as to the present invention.
  • the assembly apparatus is provided with vacuum holders 78, 79 which are mounted on the frame and each have an arcuately shaped pocket with a vacuum slot 81 connected with an associated vacuum line 83.
  • the holders 78, 79 releasably hold the upper and lower halves 75, 76 of the container with the open end portions 85, 86 (Fig. 4) thereof facing each other.
  • the clamps are then closed about these open end portions as seen in the right half of Fig. 4.
  • the clamps may first be closed and the halves advanced toward each other and entered into the upper and lower ends of the die 47.
  • the upper and lower end portions 88, 90 of the dies are provided with truncated conical guide surfaces 93., 92 which flare downwardly and upwardly respectively and at their outer ends are of a diameter greater than that of the body portions 93, 94 of the upper and lower cup sections.
  • the edge portions 85, 86 of the body portions 93, 94 are easily guided into the center portion of the die.
  • the center portion of the die has an upper cylindrical die portion with a surface 97, which is equal to substantially the outside diameter of the upper cup.
  • the upper cup is advanced into the surface 93 which rounds the lower edge portion of the upper cup by an upper pusher 100 which has a cap 101 at the lower end of rod 102 of a piston which operates in an air cylinder 103 carried by the frame.
  • the upper cup slips along the holder 78 and is guided into the cylindrical die surface 97 until the lower edge 105 of the upper cup seats upon the shoulder 106 at the bottom of the squaring surface 107.
  • the lower cup is pushed upwardly by an air or hydraulic cylinder 107 which has a base pod 108 bearing against the bottom or base 109 of the lower or male cup.
  • the edge portion 86 of the lower cup has been previously coated with an appropriate adhesive 109.
  • the edge portion 86 of the lower cup is very slightly necked-in but not deformed as it moves past the shoulder 106.
  • the inner edge of the shoulder 106 is of a diameter slightly less than the inner diameter of the upper cup, and the shoulder 106 hasa radial dimension slightly larger than the thickness of the metal of the body wall of the upper cup.
  • the fit of the lower cup edge portion into the upper edge portion merely springs the metal of the lower cup very slightly without permanent deformation and that upon release from the die, the hoop compressive forces on the edge portion 56 are slightly relieved and tensile hoop stresses develop in the edge portion 85.
  • the adhesive which is preferably thermoplastic polyolefin resins such as carboxylated polypropylene or polyethylene as well as thermosetting resins such as epoxy resins.
  • the die is opened and the upper and lower pushers separated and a vacuum withdrawn from the holders and the assembled unit is withdrawn or drops out and the following two halves are entered into the apparatus at opposite sides of the die and assembled in a continuous process.
