Abstract

In a hair feeding device configured to perform a feeding operation for pulling out flocking hairs one by one from a bundle of flocking hairs, the device includes: a head for capturing hair ends of the flocking hairs; a conveyance mechanism configured to convey the head; and a control device that controls an operation control of the feeding operation, in which the head includes a nozzle that suctions the hair ends of the flocking hairs, a gripping member that grips the flocking hair suctioned by the nozzle, and an actuator that gives a gripping pressure to the gripping member.

First claim

What is claimed is:

1. A hair feeding device configured to perform a feeding operation for pulling out flocking hairs one by one from a bundle of flocking hairs, the device comprising:
a head for capturing hair ends of the flocking hairs;
a conveyance mechanism configured to convey the head;
a detector configured to detect three-dimensional positions of the hair ends of the flocking hairs; and
a control device that controls an operation control of the feeding operation, wherein the head includes:
a nozzle that suctions the hair ends of the flocking hairs,
a gripping member that grips the flocking hair suctioned by the nozzle, and
an actuator that gives a gripping pressure to the gripping member.

2. The hair feeding device according to claim 1 , further comprising:
a feeder configured to separate the hair ends of the flocking hairs from the bundle of the flocking hairs to a head side direction, wherein
the control device controls the conveyance mechanism to move the head to advance toward the feeder to a position where the gripping member is capable of gripping the suctioned flocking hair when the nozzle is positioned at the three-dimensional position of the hair end of the flocking hair detected by the detector and the hair end of the flocking hair is suctioned by the nozzle.

3. The hair feeding device according to claim 2 , further comprising:
a flow rate detector configured to detect a flow rate of outside air suctioned from the nozzle, wherein
the control device determines whether one flocking hair is suctioned by the nozzle based on a detected flow rate of the flow rate detector, and if one flocking hair is not suctioned, the control device performs a confirmation control for performing a re-suction operation of the hair end of the flocking hair by the nozzle.

4. The hair feeding device according to claim 2 , further comprising:
a flow rate detector configured to detect a flow rate of outside air suctioned from the nozzle, wherein
the control device determines whether one flocking hair is suctioned by the nozzle based on a detected flow rate of the flow rate detector, and if one flocking hair is not suctioned, the control device executes a confirmation control for performing a re-suction operation of the hair end of the flocking hair by the nozzle respectively before and after an advancing movement of the head performed when suctioning the hair end of the flocking hair.

5. The hair feeding device according to claim 1 , further comprising:
a flow rate detector configured to detect a flow rate of outside air suctioned from the nozzle, wherein
the control device determines whether one flocking hair is suctioned by the nozzle based on a detected flow rate of the flow rate detector, and if one flocking hair is not suctioned, the control device performs a confirmation control for performing a re-suction operation of the hair end of the flocking hair by the nozzle.

6. The hair feeding device according to claim 1 , further comprising:
a flow rate detector configured to detect a flow rate of outside air suctioned from the nozzle, wherein
the control device determines whether one flocking hair is suctioned by the nozzle based on a detected flow rate of the flow rate detector, and if one flocking hair is not suctioned, the control device executes a confirmation control for performing a re-suction operation of the hair end of the flocking hair by the nozzle respectively before and after an advancing movement of the head performed when suctioning the hair end of the flocking hair.
