Abstract
A wire guide nozzle 1 is provided by a single member. The wire guide nozzle 1 is provided by a piece of long-size body 5 which has a nozzle 2 formed to penetrate the body 5 in the longitudinal direction and a wire check pin 4 assembled so as to cross the nozzle 2 and slide in the lateral direction. Provided at proper intervals in the longitudinal direction of the long-size body 5 are a plurality of wire nipping spaces 6, 7, 8 which allow rollers for interposing a wire 3 to enter the spaces.
Claims9
A wire guide nozzle for guiding a wire being fed to a wire measuring apparatus, the wire guide nozzle comprising:
- an integral long-size body having a path extending through a length of the long-size body in a longitudinal direction of the long-size body, the path allowing the wire to pass through the long-size body;
- and
- a wire check pin provided for preventing the wire from being withdrawn from the long-size body when the wire guide nozzle is not in use, the wire check pin being installed in the long-size body so as to slide in a lateral direction of the long-size body and cross the path;
- wherein the long-size body is provided, at appropriate intervals in the longitudinal direction, with a plurality of wire nipping spaces each of which allows opposing rollers to enter, the rollers being provided for nipping the wire being inserted into the path.

A wire guide nozzle unit comprising:
- a plurality of wire guide nozzles for guiding wires being fed to a wire measuring apparatus, each of the wire guide nozzles including:
- a long-size body having a path formed to penetrate therein in a longitudinal direction of the long-size body, the path allowing the wire to pass through the long-size body;
- and
- a wire check pin provided for preventing the wire from being withdrawn from the long-size body when the wire guide nozzle is not in use, the wire check pin being installed in the long-size body so as to slide in a lateral direction of the long-size body and cross the path;
- wherein the long-size body is provided, at appropriate intervals in the longitudinal direction, with a plurality of wire nipping spaces each of which allows opposing rollers to enter, the rollers being provided for nipping the wire being inserted into the path;
- and
- a nozzle base detachably mounted on a base holder of the wire measuring apparatus, the base holder being provided so as to move up and down intermittently in accordance with respective wire introducing positions that the wire measuring apparatus can occupy;
- wherein the wire guide nozzles are detachably attached to the nozzle base so as to be parallel with each other in a direction perpendicular to the moving direction of the base holder, at intervals coinciding with the intermittent movement of the base holder.

An attachment and detachment mechanism for a wire guide nozzle unit which comprises:
- a plurality of wire guide nozzles for guiding wires being fed to a wire measuring apparatus, each of the wire guide nozzles including:
- a long-size body having a path formed to penetrate therein in a longitudinal direction of the long-size body, the path allowing the wire to pass through the long-size body;
- and
- a wire check pin provided for preventing the wire from being withdrawn from the long-size body when the wire guide nozzle is not in use, the wire check pin being installed in the long-size body so as to slide in a lateral direction of the long-size body and cross the path;
- wherein the long-size body is provided, at appropriate intervals in the longitudinal direction, with a plurality of wire nipping spaces each of which allows opposing rollers to enter, the rollers being provided for nipping the wire being inserted into the path;
- and
- a nozzle base detachably mounted on a base holder of the wire measuring apparatus, the base holder being provided so as to move up and down intermittently in accordance with respective wire introducing positions that the wire measuring apparatus can occupy;
- wherein the wire guide nozzles are detachably attached to the nozzle base so as to be parallel with each other in a direction perpendicular to the moving direction of the base holder, at intervals coinciding with the intermittent movement of the base holder;
- the attachment and detachment mechanism comprising:
- an end plate mounted on the lower end of the base holder, for supporting the lower end of the nozzle base;
- a claw part mounted on the upper end of the base holder, for disengageably engaging with the upper end of the nozzle base being supported by the end plate;
- an urging unit mounted on the base holder, for urging the claw part for engagement with the upper end of the nozzle base by spring force;
- and
- an engagement releasing unit which is arranged so as to coincide with the urging unit in process of the base holder's upward and downward movement and which allows the claw part to move in the direction to release the engagement with the nozzle base at the coincidence position, in opposition to the spring force.
