Japanese Patent No. 3240771

  However, each stone forming the rigid concave surface of the shoe assembly of the tape wrap device is manufactured according to the workpiece shaft diameter or shaft width, and the interval between adjacent workpiece shafts, and the specific workpiece shaft Because it is limited to machining only the diameter or shaft width, the interval between adjacent workpiece axes, if the workpiece shaft diameter or shaft width, the spacing between the axes is different, it has multiple dedicated rigidity In the tape wrap apparatus, it is necessary to change the setup to replace the shoe assembly having a stone that forms a concave surface, and in Patent Document 1, a large number of integrated cassette shoe assemblies can be stored easily. In addition, since the setup change time is long, the operation rate of the tape wrap apparatus is lowered.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a tape wrap apparatus having an integrated cassette shoe assembly in which a pair of opening and closing arms for supporting a shoe assembly and a clamp shaft for opening and closing the arms are assembled as an integrally replaceable cassette. It is an object of the present invention to provide a tape wrap device that can easily store an integrated cassette shoe assembly and does not take time for setup change.

Therefore, the present invention provides a shoe assembly having an abrasive-coated tape , and a concave surface fixed to a pair of opening and closing arms that press the abrasive-coated surface of the tape into contact with the surface of a workpiece such as a crankshaft. A pair of opening and closing arms that support the shoe assembly and a clamp shaft that opens and closes the arm as an integrally replaceable cassette. The integrated cassette shoe assembly has a cassette side guide rail attached to the top, and can be attached to an ATC side guide rail that can be arranged in parallel. The integrated cassette shoe assembly is attached to the ATC side guide rail. When this occurs, the anti-back stopper provided on the ATC side guide rail body is locked to prevent misalignment. Remove case, to release the lock by pushing the push pin of the anti-back release device provided on the ATC side guide rail body, is to remove the integrated cassette shoe assemblies, the anti-back stopper, the ATC side A guide rail main body shaft, a ratchet rotatably supported by the shaft, and a spring for urging the ratchet tip to the ATC side guide rail. The anti-back releasing device has a slide tip for lifting the ratchet tip above the rear end of the cassette side guide rail against the bias of the spring, and the slide tip. A push pin coupled to the slide, and the ratchet via the slide tip by pushing the push pin It has solved the problems of the conventional products described above by providing a tape wrap system, characterized in that to release the lock lift the end.

  With such a configuration, the integrated cassette shoe assembly includes a pair of opening and closing arms that support the shoe assembly and a clamp shaft that opens and closes the arm as an integrally replaceable cassette. When the assembly side guide rail is attached to the ATC side guide rail, the assembly side guide rail is attached to the ATC side guide rail. The anti-back stopper provided on the ATC side guide rail body is locked to prevent misalignment. When removing from this state, the push pin of the anti-back release device provided on the ATC side guide rail body is pressed to release the lock. And removing the one-piece cassette shoe assembly so that a plurality of one-piece cassette shoe assemblies are assembled. Exchange easy to save the, was intended to provide a tape wrap device a changeover time is not applied.

Preferably , the plurality of ATC-side guide rails arranged in parallel are capable of turning to an integrated cassette shoe assembly replacement position rotated about 90 ° from a magazine part replacement position that can be automatically replaced with the processing machine body. Thus, the integrated cassette shoe assembly can be easily replaced manually at a safe position.

  Embodiments of the present invention will be described with reference to the drawings. 1 is a schematic plan view of an ATC-equipped tape wrap device according to an embodiment of the present invention, FIG. 2 is a schematic side view seen from the direction B of FIG. 1, FIG. 3A is a partially enlarged view of part A of FIG. b) Schematic side view with one integrated cassette shoe assembly of (a) removed, (c) with the integrated cassette shoe assembly attached to the ATC side guide rail as viewed from direction C in FIG. (D) is a partial enlarged side view of the anti-back stopper 10 of (c).

  As shown in FIG. 3 (b), the tape wrapping apparatus according to the embodiment of the present invention includes a relatively incompressible abrasive-coated tape 1 and an abrasive-coated surface of the tape 1 covered with a shaft object such as a crankshaft. In a tape wrapping apparatus comprising a shoe assembly 3, 3 having a relatively rigid concave surface 2, 2 fixed to a pair of open / close arms 4, 4 which are brought into contact with and pressed against the surface of a workpiece 7 (FIG. 1) A pair of open / close arms 4 and 4 that support the three-dimensional bodies 3 and 3, a clamp shaft 5 that opens and closes the arms 4 and 4, a tape supply holder (not shown), and a tape take-up holder that are assembled together as an integrally replaceable cassette 6. It has a body cassette shoe assembly 6. Each integrated cassette shoe assembly 6 has a cassette side guide rail 8 attached to the top, and as shown in FIGS. 3 (c) and 3 (d), a plurality of integrated cassette shoe assemblies 6 are arranged in parallel. When installed on the ATC side guide rail 22 and mounted on the ATC side guide rail 22 at the cassette storage position indicated by the dotted line position H in FIG. The anti-back stopper 10 is locked to prevent misalignment, and when removing from that state, the push pin 24 of the anti-back releasing device 20 provided on the ATC side guide rail body 21 is pressed to release the lock, and the integrated cassette The shoe assembly 6 is removed. In operation, the unclamped integrated cassette shoe assembly 6 in FIG. 3B is attached to a tape wrap device main body 9 (FIG. 1) (not shown) and attached to the tape wrap device main body 9 (not shown). When a pressing device such as a hydraulic cylinder pushes the end surface of the clamp shaft 5, the open / close arms 4 and 4 are closed and a clamped state is established. After this, the workpiece 7 of the shaft is rotated by a rotating device 26 (FIG. 1), and the surface of the workpiece 7 is microfinished very precisely by the abrasive-coated surface of the tape 1.

  In the embodiment of the present invention, the anti-back stopper 10 is a ratchet 13 biased by a spring 11 provided on the ATC side guide rail body 21 so as to lock the rear end 15 of the cassette side guide rail 8.
