Rivet holding container and rivet feed system for automatic feed blind rivet setting tool
An elongated rivet bag holding a quantity of blind rivets ready for use in an automatic rivet setting tool. The rivets are connected along an elongated flexible rivet carrying strip by having a distal portion of each mandrel inserted or pierced through the carrying strip and positioned and stored in a random orientation within the rivet bag which is openable at an upper end thereof to render the rivets and strip ready for use. A blind rivet feed device for feeding the rivet-loaded strip into the nose of the automatic rivet setting tool is also provided along with a rivet strip collection bag for the empty strip.
1. A container holding a quantity of blind rivets ready for use in an automatic rivet setting tool, comprising:
an elongated rivet bag releasably closed at an upper end thereof for storage and dependently connectable at said upper end to an elongated laterally extending spindle of the rivet setting tool;
said rivets being connected in spaced relation along the length of an elongated flexible rivet carrying strip by having a distal portion of each mandrel inserted or pierced through said carrying strip;
said rivets on said carrying strip being positioned in a random orientation within said rivet bag with one end of said carrying strip being positioned at or adjacent to a lower end of said rivet bag while another end of said carrying strip is positioned immediately adjacent to and within or extending from said upper end of said rivet bag.
2. A blind rivet storage and feed system for an automatic rivet setting tool, comprising:
an elongated strip of thin flexible material having a lead end and a plurality of blind rivets connected in spaced apart relation along the length of said flexible strip by having at least the distal portion of each mandrel pierced through and retained within said flexible strip;
said flexible strip slidably extending through a transverse feed slot formed through a rivet table of the rivet setting tool, the feed slot orthogonally intersecting a longitudinal mandrel receiving slot extending laterally in one direction from a rivet table aperture to an outer surface of the rivet table;
a feed device attached to the tool and being engagable with a lead end portion of said flexible strip for pulling said flexible strip through the transverse slot to draw each mandrel of each blind rivet held in said flexible strip and positioned immediately adjacent the rivet table one at a time into the rivet table aperture through the mandrel receiving slot;
an elongated rivet bag releasably closed at an upper end thereof for storage and dependently connectable at said upper end to an elongated laterally extending spindle of the too;
said rivets on said carrying strip being positioned in a random orientation within said rivet bag with one end of said carrying strip being positioned at or adjacent to a lower end of said bag while said lead end portion is positioned immediately adjacent to and within or extending from said upper end of said rivet bag.
3. A blind rivet feed system for an automatic rivet setting tool, the tool utilizing a continuous rivet delivery arrangement including an elongated strip of thin flexible material having a lead end and a plurality of blind rivets connected in spaced apart relation along the length of said flexible strip by having at least the distal portion of each mandrel pierced through and retained within said flexible strip, the flexible strip slidably extending through a transverse feed slot formed through a rivet table of the rivet setting tool, the feed slot orthogonally intersecting a longitudinal mandrel receiving slot extending laterally in one direction from a rivet table aperture to an outer surface of the rivet table, said feed system comprising:
a feed device attached or attachable to the tool and being pullably engagable with a lead end portion of said flexible strip for pulling said flexible strip through the transverse slot to draw each mandrel of each blind rivet held in said flexible strip and positioned immediately adjacent the rivet table one at a time into the rivet table aperture through the mandrel receiving slot;
a carrying strip collection bag positioned downstream of, and in alignment with, a flexible strip discharge area of said feed device wherein said flexible strip without blind rivets is fed into said collection bag.
4. A blind rivet feed system as set forth in claim 3 , wherein said feed device includes:
first and second wheels having closely interengaging perimeters and arranged in edge-to-edge fashion to drivingly engage with said carrying strip passing therebetween wherein said carrying strip is tensioned and pulled through and from the rivet table as said wheels are rotated.
5. A blind rivet feed system as set forth in claim 4 , further providing:
a removable mandrel collection container releasably attached to a rear portion of said feed device for safely collecting mandrels after being fractured as each blind rivet is set by said tool.
