Mattress manufacturing process and apparatus
View Patent ↗A process and apparatus for manufacturing a mattress generally includes an insertion station for supporting an innercore, a movable platform for supporting a bucket, and an adhesive applicator intermediate the insertion station and the movable platform. The adhesive applicator is configured to apply adhesive prior to or simultaneous with insertion of the innercore unit into a cavity of the bucket. The innercore unit is gravity fed from an elevated surface of the insertion station into a leading edge of the bucket cavity to form the innercore unit and bucket assembly. The process and apparatus minimizes and/or eliminates manual labor as it relates to the manufacture of the innercore unit and bucket assembly.
1. A process for manufacturing an innercore unit and bucket assembly, comprising:
automatically applying an adhesive from a static position onto a selected surface of a moving bucket, wherein the bucket comprises a base layer and a side rail assembly attached to the base layer and disposed about a periphery thereof to define a bucket cavity; and
inserting an innercore unit into the bucket cavity at a leading edge thereof from an elevated support surface positioned above the bucket, wherein inserting the innercore unit is gravity assisted, and wherein the innercore unit contacts the adhesive on the selected surface when fully inserted into the cavity to form the innercore unit and bucket assembly.
2. The process of claim 1 , wherein applying the adhesive comprises spraying a pattern of the adhesive onto the surface.
3. The process of claim 1 , wherein the adhesive comprises a hot melt adhesive.
4. The process of claim 1 , wherein applying the adhesive is prior to inserting the innercore unit into the bucket cavity.
5. The process of claim 1 , wherein applying the adhesive is simultaneous with inserting the innercore unit into the bucket cavity.
6. The process of claim 1 , wherein applying the adhesive is metered.
7. The process of claim 1 , wherein the innercore unit comprises coil springs and/or foam.
8. The process of claim 1 , wherein applying the adhesive onto the selected surface of the bucket comprises moving the bucket on a movable platform to position the leading edge of the cavity to be underneath an adhesive applicator configured for applying the adhesive.
9. The process of claim 1 , wherein inserting the innercore unit into the bucket cavity to form the innercore unit and bucket assembly comprises moving a leading edge of the innercore unit from the elevated support surface and inserting the leading edge of the innercore unit onto the leading edge of the cavity, wherein gravity assists in inserting a remainder of the innercore unit into the cavity to form the innercore unit and bucket assembly.
