Abstract

A component supplying device includes a body portion including a component pick-up position, a tape path, first and second transfer portions, a control portion, and an input portion. The control portion includes a discharge processing portion which executes a discharge process in response to an instruction at the input, and a transfer processing portion which executes a transfer process after the discharge process. In the discharge process, a first component supply tape is transferred by the first transfer portion away from the first transfer position so that at least a part of the first component supply tape is discharged outside the body portion while holding the components. In the transfer process, a second component supply tape that is at the second transfer position is transferred by the second transfer portion toward the first transfer position, and transferred by the first transfer portion toward the component pick-up position.

First claim

The invention claimed is:

1. A component supplying device configured to transfer a first component supply tape and a second component supply tape each including components thereon, the component supplying device comprising:
an input system configured to receive an instruction input from an outside of the component supply device;
a feeder comprising:
a body including a first section in which a first transfer position and a component pick-up position are defined and a second section in which a second transfer position is defined, the first transfer position being between the component pick-up position and the second transfer position;
a first transfer mechanism disposed in the first section; and
a second transfer mechanism disposed in the second section; and

a controller configured to:
determine whether the first component supply tape is present at the first transfer position in response to the instruction input in the input system;
if the first component supply tape is present at the first transfer position, control the first transfer mechanism to discharge at least a part of the first component supply tape including the components out of the feeder;
when the control of the first transfer mechanism is completed, control the second transfer mechanism to transfer the second component supply tape from the second transfer position to the first transfer position; and
when the control of the second transfer mechanism is completed, control the first transfer mechanism to transfer the second component supply tape to the component pick-up position.

2. The component supplying device according to claim 1 , wherein
the input system includes a button configured to be operated by an operator to input the instruction, and
the controller is further configured to:
determine whether the first component supply tape is present at the first transfer position regardless of conditions of the first component supply tape in the feeder after the controller receiving the instruction input from the input system.

3. The component supplying device according to claim 1 , wherein
the body further includes a tape cavity passing through the body at least in a direction in which the first component supply tape is transferred, the tape cavity is branched at a branch point in the second section and includes:
a first cavity portion including a first opening in a first outer surface of the body at an end of the first section, the first cavity portion extending between the branch point and the first opening;
a second cavity portion including a second opening in a second outer surface of the body at the second section, the second cavity portion extending between the branch point and the second opening; and
a third cavity portion including a third opening in the second outer surface of the body at the second section, the third cavity portion extending between the branch point and a third opening, wherein

the first transfer position and the component pick-up position are defined in the first cavity portion,
the second transfer position is defined in the second cavity portion, and
the body includes a through hole at the component pick-up position.

4. The component supplying device according to claim 3 , wherein
the feeder further includes a third transfer mechanism disposed in the second section,
a third transfer position is defined in the third cavity portion, and
the controller is further configured to:
if the first component supply tape is present at the first transfer position, control the first transfer mechanism to transfer the first component supply tape to the third transfer position, in response to the instruction input in the input system; and
when the control of the first transfer mechanism is completed, control the third transfer mechanism to discharge at least the part of the first component supply tape including the components at the third transfer position out of the feeder through the third opening.

5. The component supplying device according to claim 4 , wherein
the first transfer mechanism includes at least a first rotating member, the first transfer mechanism is disposed such that a part of the first rotating member is in the first cavity portion at the transfer position that is between the branch point and the component pick-up position, the part of the first rotating member is configured to contact with and urge one of the first component supply tape and the second component supply tape when the one of the first component supply tape and the second component supply tape is present at the first transfer position,
the second transfer mechanism includes at least a second rotating member, the second transfer mechanism is disposed such that a part of the second rotating member is in the second cavity portion at the second transfer position that is between the branch point and the second opening, the part of the second rotating member is configured to contact with and urge the second component supply tape when the second component supply tape is present at the second transfer position, and
the third transfer mechanism includes at least a third rotating member, the third transfer mechanism is disposed such that a part of the third rotating member is in the third cavity portion at the third transfer position that is between the branch point and the third opening, the part of the third rotating member configured to contact with and urge the first component supply tape when the one of the first component supply tape is present at the third transfer position.

6. The component supplying device according to claim 4 , wherein
the body further includes a path member disposed at the branch point to be movable between inside and outside of the second cavity portion, and
the controller is further configured to:
if the first component supply tape is present at the first transfer position, place the path member inside the second cavity portion to close the second cavity portion, in response to the instruction input in the input system prior to the control of the first transfer mechanism; and
when the control of the first transfer mechanism is completed, move the path member to outside the second cavity portion to open the second cavity portion prior to the control of the second transfer mechanism.

7. The component supplying device according to claim 3 , wherein
the third opening is at a bottom of the second section,
the third cavity portion is sloped downward from the branch point to the third opening, and
the controller is further configured to:
if the first component supply tape is present at the first transfer position, control the first transfer mechanism to discharge at least the part of the first component supply tape including the components through the third opening out of the feeder, in response to the instruction input to the input portion.

8. The component supplying device according to claim 4 , wherein
the feeder further comprises a first detector configured to detect the first component supply tape at a first detection position defined in the third cavity portion between the third transfer position and the branch point, and
the controller is further configured to:
if the first detector fails to detect the first component supply tape after the control of the first transfer mechanism is completed, assume that discharge of the first component supply tape is completed; and
when it is assumed that the discharge of the first component supply tape is completed, stop controlling the third transfer mechanism.

9. The component supplying device according to claim 1 , further comprising:
a display system including a display screen; and
a monitoring timer, wherein
the feeder further includes a second detector conf
