Abstract
A tire derimming apparatus is disclosed having one ram for forcing a tire and rim combination through a restricted opening. Tires exiting the restricted opening are disconnected from the rim on which they were mounted. The apparatus further comprises a feeding arrangement which ensures that one tire and wheel combination at a time enters the derimming section.
Claims22
A tire derimming machine comprising:
- a) an elongated frame;
- b) a single ram supported at one end of the frame;
- c) a mandrel attached to the frame said mandrel including angled and inclined plates, said plates being angled and inclined such that a tire/rim combination pushed completely therethrough by said ram is reduced in outer dimension to uncouple the tire from the rim.
A tire derimming machine comprising:
- a) an elongated frame;
- b) a single ram supported at one end of the frame;
- c) a mandrel having converging plates mounted centrally on said frame said plates converging in the direction of forward stroke of the ram on an angle in the range of about 30.degree. to about 50.degree., said plates being wider at a mouth thereof and narrower at a throat thereof said throat being located in an area of said frame of about a point at which the forward stroke of the ram ends;
- d) a feeder rack supported on said frame section kitty corner to and above said mandrel said feeder rack having a diameter sufficient to accept a tire/wheel combination, said feeder rack being disposed immediately above a feeder plate operatively attached to said ram such that said ram imparts to said feeder plate a reciprocating movement in an axial direction along said frame, said feeder plate reciprocating out from under a tire/wheel combination in the feeder rack such that a tire/wheel combination is transported to the mandrel upon the feeder plate cycling back to its start position;
- and
- e) a shaker table resiliently mounted on said frame and extending from said mandrel in a direction away from the end of the frame supporting the ram, said shaker table being operatively connected to a shaking means and including a cut out at an end of the shaker table distal from the end proximate the mandrel;
- whereby said ram urges a tire/wheel combination through said mandrel while leading a sequentially, additional tire/wheel combination from said feeder rack to said feeder plate to said mandrel to said shaker table whereon said tire and wheel are separated.
4 more elements
A tire derimming machine comprising:
- a) an elongated frame;
- b) a ram supported at one end of said frame, said ram having a head;
- c) two guide plates supported by said elongated frame said guide plates being positioned one on either side of a centerline of said elongated frame, each plate having a first end and a second end said first ends of said plates being located at a greater distance from said centerline than said second ends of said plates such that said plates, in combination, form a throat which constricts in a direction of forward ram movement, said ram extending from a non-extended position to a telescoped position wherein said head of said ram extends beyond a first plane defined by said first ends of said plates and beyond a second plane defined by said second ends of said plates thus forcing a tire and rim combination to reduce size and pass through said second plane of said plates.
