A motor related to a reel cassette among a plurality of the reel cassettes, in the condition where there is a shortage of a component in a component supply tape and an error has occurred (for example, a component adsorption error, or an image processing error) attributable to the supplied component, is operated so that a sprocket driving mechanism portion is lowered against a spring, a sprocket is lowered to a retract position, engagement of the sprocket with a sprocket hole of the component supply tape is released, and a clamp state of the reel cassette is released with a clamp member retracted downward from the reel cassette. Moreover, a display unit of an operation panel displays that only the reel cassette subjected to automatic clamp release is in a clamp release state.
1. A tape feeder configured so that a reel cassette, which guides a component supply tape drawn out from a tape reel to a component adsorption position, is removably mounted on a feeder main body, the tape feeder comprising:
a sprocket driving mechanism portion that feeds the component supply tape to the component adsorption position by rotating a sprocket while causing teeth of the sprocket to be engaged with sprocket holes of the component supply tape;
an actuator that moves the sprocket driving mechanism portion upward and downward between an engagement position where the teeth of the sprocket are in a state of being engaged with the sprocket holes of the component supply tape and a retract position where the teeth of the sprocket are positioned below the sprocket holes of the component supply tape;
a clamp member that is moved upward and downward integrally with the sprocket driving mechanism portion, and clamps the reel cassette when the sprocket driving mechanism portion is lifted to the engagement position; and
automatic clamp release means for performing automatic clamp release, in which a clamp state of the reel cassette by the clamp member is released, by operating the actuator and lowering the sprocket driving mechanism portion to the retract position when it is detected that the reel cassette has to be removed from the feeder main body.
2. The tape feeder according to claim 1 ,
wherein the automatic clamp release means determines that the reel cassette has to be removed from the feeder main body and performs the automatic clamp release when there is at least one of a shortage of a component in the component supply tape and an error attributable to the supplied component occurs.
3. The tape feeder according to claim 1 ,
wherein a plurality of the sprocket driving mechanism portions, a plurality of the actuators, and a plurality of the clamp members are disposed in the feeder main body,
wherein a plurality of reel cassettes are removably mounted on the feeder main body independently from each other, and the teeth of the sprocket of the respective sprocket driving mechanism portions are engaged with the sprocket holes of the component supply tapes of the respective reel cassettes and the respective reel cassettes are configured to be clamped by the respective clamp members when the respective sprocket driving mechanism portions are lifted to the engagement position, and
wherein the automatic clamp release means determines whether or not the reel cassette has to be removed from the feeder main body for each of the reel cassettes and performs the automatic clamp release only for the reel cassette which has to be removed from the feeder main body.
4. The tape feeder according to claim 3 ,
wherein an operation panel is disposed so as to display whether each of the reel cassettes is in a clamp release state or the clamp state.
5. The tape feeder according to claim 2 ,
wherein a plurality of the sprocket driving mechanism portions, a plurality of the actuators, and a plurality of the clamp members are disposed in the feeder main body,
wherein a plurality of the reel cassettes are removably mounted on the feeder main body independently from each other, and the teeth of the sprockets of the respective sprocket driving mechanism portions are engaged with the sprocket holes of the component supply tapes of the respective reel cassettes and the respective reel cassettes are configured to be clamped by the respective clamp members when the respective sprocket driving mechanism portions are lifted to the engagement position, and
wherein the automatic clamp release means determines whether or not the reel cassette has to be removed from the feeder main body for each of the reel cassettes and performs the automatic clamp release only for the reel cassette which has to be removed from the feeder main body.
6. A tape feeder configured so that a reel cassette, which guides a component supply tape drawn out from a tape reel to a component adsorption position, is removably mounted on a feeder main body, the tape feeder comprising:
a sprocket driving mechanism portion that feeds the component supply tape to the component adsorption position by rotating a sprocket while causing teeth of the sprocket to be engaged with sprocket holes of the component supply tape;
an actuator that moves the sprocket driving mechanism portion upward and downward between an engagement position where the teeth of the sprocket are in a state of being engaged with the sprocket holes of the component supply tape and a retract position where the teeth of the sprocket are positioned below the sprocket holes of the component supply tape;
a clamp member that is moved upward and downward integrally with the sprocket driving mechanism portion, and clamps the reel cassette when the sprocket driving mechanism portion is lifted to the engagement position; and
a controller programmed to perform automatic clamp release, in which a clamp state of the reel cassette by the clamp member is released, by operating the actuator and lowering the sprocket driving mechanism portion to the retract position when it is detected that the reel cassette has to be removed from the feeder main body.
