TEXTILE MACHINERY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a textile machinery.
2. Description of the Related Art
Conventionally, as techniques of such field, there are
known techniques described in Japanese Unexamined Patent
Publication No. 5-8943 (Patent Docioment 1) , Japanese Unexamined
Patent Publication No. 2005-330596 (Patent Document 2), and
Japanese Unexamined Patent Publication No. 2 007-2 62 607 (Patent
Document 3). Patent Document 1 describes an automatic winder
including a plurality of winding units, and two doffing carts
respectively adapted to move between the winding units to
perform a doffing operation. When a winding unit (a doffing
requiring unit) which requires the doffing operation exists,
the automatic winder moves the doffing cart in a direction
towards the doffing requiring unit located closest to a current
position of the doffing cart. Assigned regions of the two
doffing carts to perform the doffing operation are overlapped,
and one doffing cart moves to an opposite side such that the
doffing carts do not interfere with one another. |
Patent Document 2 describes a textile machinery including
a plurality of spinning units, and a plurality of operation carts
adapted to travel among the plurality of spinning units. The
operation carts of the textile machinery execute the operation
within a predefined operation region. Since the operation carts
obtain current positions of one another, in case a certain
operation cart becomes a hindrance when another operation cart
moves, the operation cart that becomes a hindrance in the
movement is retreated in advance.
Patent Document 3 describes a textile machinery including
a plurality of spinning units, and a plurality of operation carts

We claim:
1. A textile machinery comprising:
a plurality of processing units adapted to perform yarn
processing,
a plurality of operation carts, each operation cart being
adapted to travel and execute an operation with respect to the
processing units, and
a control section adapted to select an operation executing
cart from the plurality of the operation carts in accordance
with an operation request from an operation requesting unit,
which is one of the plurality of the processing units, the
operation executing cart being adapted to execute an operation
with respect to the operation requesting unit,
wherein at least a portion of the plurality of the
processing units is arranged within an exclusive region where
the operation requesting unit can receive the operation from
only one of the operation carts, and at least a different portion
of the plurality of the processing units is arranged within an
overlapping region where the operation requesting unit can
receive the operation from the plurality of the operation carts,
the operation cart is adapted to execute the operation
with respect to at least one processing unit arranged within
the exclusive region and at least one processing unit arranged
within the overlapping region, and
when the operation requesting unit is located within the
overlapping region, the control section is adapted to select
the operation executing cart for executing the operation with
respect to the operation requesting unit located within the
overlapping region in accordance with an occurrence of the
operation request within the exclusive regions of the plurality
of the operation carts capable of executing the operation with
respect to such an operation requesting unit.
2. The textile machinery according to claim 1, wherein
