Abstract: Disclosed is a continuous riveter capable of firing blind rivets in succession to caulk sheet metal or the like. A seal member 71 located on the oil chamber 6 side and a seal member 72 located on the air chamber 4 side are provided in an oil cylinder 1 where an oil piston 2 separates the oil chamber 6 of the oil cylinder 1 from the air chamber 4 of an air cylinder 3, and a portion of the oil cylinder 1 which is between seal members 71 and 72 is provided with an air vent 19; and a seal member 74, 76 located on the oil chamber 16 side and a seal member 73, 77 located on the air chamber 14, 15 side are provided in a jaw case piston 20 and in a nose piston 28, the seal members 74, 76 and 73, 77 sealing an area between the oil chamber 16 and the air chamber 14, 15, and the pistons 20 and 28 between the seal members 74, 76 and 73, 77 are each provided with an air vent 75, 78.

Abstract: A device for loading a rivet and the like in a rivet holder belt which can continuously and securely load a large number of rivets and the like to the rivet holder belt includes: a hopper 11 for storing the rivets and the like at random; a chute 14 which is continuous from the hopper 11 to guide the rivets and the like that are contained in the hopper 11 to a delivery position of a rivet wheel 15; the rivet wheel 15 which rotates to receive the rivets and the like from the lower end of the chute 14 and store them one by one in each of plural grooves 29 that are formed in the rims of flange bodies; a pushing member 42 which is provided to face the circumference of the rivet wheel 15 to push the rivets and the like resting in the grooves 29 of the rivet wheel 15 into holding notches 37 of a rivet holder belt 36 that is guided along the rivet wheel 15; and a sprocket 35 which is provided in a trunk 27 of the rivet wheel 15 and feeds the rivet holder belt 36 while engaging with engagement holes 38 that are opened

Abstract: Although the conventional continuous riveting machine was able to use exclusively a special blind rivet having a longer core-stem than that of the standard type, the continuous riveting machine according to the present invention is able to use the standard blind rivet and also able to recover separately torn core rivet stems and a blind rivet-holding belt made of plastic material enabling the supply of blind rivets in series. When a lower piston 600 descends in a jaw cylinder 400, a nose piece 620 integrated in one piece with the lower piston 600 also descends while bending downwardly plastic upper and lower tabs of the blind rivet-holding belt, and holding the blind rivet. Torn-core-stems are absorbed and stored in a torn core rivet stems storing case installed on the upper portion of the jaw cylinder by applying vacuum air absorbing force generated in a vacuum ejector.

Abstract: A rivet inserting device for inserting multiple rivets and the like into a rivet-holding belt or device omprising a hopper containing the rivets, a rotatable rivet-receiving wheel having a plural of flanges installed on both sides of a core portion, and having grooves receiving the rivets one by one displaced in the specified distance on the peripheries of the flanges, a rivet-feeding route installed between the hopper and the rivet-receiving wheel, shaped as a slit having a width lager than the diameter of the stem portions of rivets, and smaller than the diameter of the head portion thereof. A revolving roller is located in the neighborhood of the hopper across the rivet-feeding route and is provided with a groove along the axial direction on the periphery thereof.
