Definitions

the present invention relates to a winding apparatus for winding a wire on an outer peripheral of a rotating winding tool parallel to a rotation axis, a manufacturing facility and a winding method using the same, and a finished product manufacturing method.
a wire winding method is known according to which a coil bobbin serving as a winding tool is mounted on a winding tool holder and rotated and a wire fed from a nozzle is rolled up and wound on the coil bobbin. Further, it is known as a method for rotating a winding tool holder to couple a plurality of winding tool holders to a rotary shaft of a single motor via a belt and simultaneously rotate the plurality of winding tool holders in the same direction by the single motor.
the belt may be worn or stretched and become slackened due to use. This may cause ridges of the belt to ride over and skip ridges of pulley(s) provided on the rotary shaft of the motor or the winding tool holders and cause a deviation of a rotational position. Further, energy loss at contact parts is large due to there being many mechanical contact parts and there is also a problem of heat generation due to wear.
JP2002-43157A discloses a winding apparatus in which a plurality of winding tool holders rotatable with winding tools mounted thereon are pivotally supported on a single base so as to be parallel to each other and rotational drive sources are respectively individually coupled to the plurality of winding tool holders.
a controller causes a plurality of the rotational drive sources separately provided on the winding tool holders to rotate in synchronization with each other.
a plurality of wound products of the same type can be obtained at one time by rotating the plurality of rotational drive sources in synchronization with each other. Since a belt coupling mechanism is not used in this winding apparatus, deviation of a rotational position due to the wear of a belt is not caused, energy loss is little, and there is no concern for heat generation due to wear.
wound products 3a, 3b having different specifications are necessary.
winding apparatuses 1, 2 as the specifications have to be arranged along the conveyor 4.
cost increases due to the necessity to prepare the plurality of winding apparatuses 1, 2 and a relatively large installation space is necessary since the plurality of winding apparatuses 1, 2 are installed with the space necessary for an operation provided therebetween.
the present invention aims to provide a winding apparatus capable of simultaneously manufacturing a plurality of types of wound products and a winding method using the same.
the present invention aims to provide a manufacturing facility and a finished product manufacturing method capable of improving productivity by assembling a plurality of types of wound products without loss.
a winding apparatus for winding wires around rotating winding tools, includes a plurality of rotatable winding tool holders respectively pivotally supported on a base, the winding tools being mountable on the winding tool holders, a plurality of rotational drive sources respectively independently coupled to the plurality of winding tool holders, and control means for controlling the plurality of rotational drive sources, the control means includes a plurality of electrical control devices connected to at least one of the rotational drive sources, the electrical control devices driving the rotational drive sources in accordance with control programs, a storage device storing a plurality of the control programs, and a selection circuit for providing the plurality of control programs stored in the storage device to the plurality of electrical control devices, and the selection circuit is configured to be able to provide different ones of the control programs to different ones of the electrical control devices.
Claim 1 specifies the details of this apparatus.
Claim 2 specifies the method.
