Abstract

A feeder exchanging carriage includes a reel holder which holds a reel on which a carrier tape which stores electronic components is wound, a feeder holder which holds a tape feeder which performs a feeding operation of the carrier tape, and a base unit which is provided with a pair of front wheels and a pair of rear wheels, and a telescopic unit (a front base and a rear base) which expands and contracts an interval between the pair of front wheels and the pair of rear wheels. In a state where the feeder exchanging carriage is mounted to an electronic component mounter, the interval between the front and rear wheels is contracted by the telescopic unit, and in a state where the feeder exchanging carriage is not mounted to an electronic component mounter, the interval between the front and rear wheels is expanded by the telescopic unit.

First claim

What is claimed is:

1. A feeder exchanging carriage comprising:
a reel holder which holds a reel on which a carrier tape which stores electronic components is wound;
a feeder holder which holds a tape feeder which performs a feeding operation of the carrier tape;
a base unit provided with a pair of front wheels, a pair of rear wheels, and a telescopic unit which is capable of expanding and contracting an interval between the pair of front wheels and the pair of rear wheels,
a handle unit which is provided on the rear wheel side of the base unit and is collapsible; and
a linking unit which engages the handle unit with the telescopic unit and transmits a movement caused by a folding operation and a lifting operation of the handle unit to the telescopic unit,
wherein in a state in which the feeder exchanging carriage is mounted to an electronic component mounter, the interval is contracted by the telescopic unit,
wherein in a state in which the feeder exchanging carriage is not mounted to an electronic component mounter, the interval is expanded by the telescopic unit
wherein the interval is contracted by the folding operation of the handle unit, and
wherein the interval is expanded by the lifting operation of the handle unit.

2. The feeder exchanging carriage of claim 1 , further comprising:
a folding lock unit which suppresses the folding operation of the handle unit in a state in which the handle unit is pulled up.

3. A feeder exchanging carriage comprising:
a reel holder which holds a reel on which a carrier tape which stores electronic components is wound;
a feeder holder which holds a tape feeder which performs a feeding operation of the carrier tape;
a base unit provided with a pair of front wheels, a pair of rear wheels, and a telescopic unit which is capable of expanding and contracting an interval between the pair of front wheels and the pair of rear wheels;
a sliding lock unit which suppresses the contraction of the telescopic unit,
a handle unit which is provided on the rear wheel side of the base unit and is collapsible; and
a linking unit which engages the handle unit with the telescopic unit and transmits a movement caused by a folding operation and a lifting operation of the handle unit to the telescopic unit
wherein in a state in which the feeder exchanging carriage is mounted to an electronic component mounter, the interval is contracted by the telescopic unit,
wherein in a state in which the feeder exchanging carriage is not mounted to an electronic component mounter, the interval is expanded by the telescopic unit and the contraction of the interval is suppressed by the sliding lock unit,
wherein the interval is contracted by the folding operation of the handle unit, and
wherein the interval is expanded by the lifting operation of the handle unit.

4. The feeder exchanging carriage of claim 3 , further comprising:
a lifting and lowering unit which supports the feeder holder such that the feeder holder may be lifted and lowered freely in relation to the base unit,
wherein the sliding lock unit includes a locking member which is connected to the feeder holder, and
wherein the locking member allows expansion and contraction of the telescopic unit in a state in which the feeder holder is lifted, and suppresses expansion and contraction of the telescopic unit in a state in which the feeder holder is lowered.

5. A feeder exchanging carriage comprising:
a reel holder which holds a reel on which a carrier tape which stores electronic components is wound;
a feeder holder which holds a tape feeder which performs a feeding operation of the carrier tape;
a base unit provided with a pair of front wheels, a pair of rear wheels, and a telescopic unit which is capable of expanding and contracting an interval between the pair of front wheels and the pair of rear wheels;
a sliding lock unit which suppresses the contraction of the telescopic unit; the feeder exchanging carriage further comprising:
a lifting and lowering unit which supports the feeder holder such that the feeder holder may be lifted and lowered freely in relation to the base unit,
wherein in a state in which the feeder exchanging carriage is mounted to an electronic component mounter, the interval is contracted by the telescopic unit,
wherein in a state in which the feeder exchanging carriage is not mounted to an electronic component mounter, the interval is expanded by the telescopic unit and the contraction of the interval is suppressed by the sliding lock unit,
wherein the sliding lock unit includes a locking member which is connected to the feeder holder, and
wherein the locking member allows expansion and contraction of the telescopic unit in a state in which the feeder holder is lifted, and suppresses expansion and contraction of the telescopic unit in a state in which the feeder holder is lowered.

6. The feeder exchanging carriage of claim 5 , further comprising:
a sensor which detects a state in which the telescopic unit is expanded,
wherein when the state in which the telescopic unit is expanded is detected by the sensor, the feeder holder is supported by the lifting and lowering unit and is lowered.
