DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire winding device for winding a long supply wire into a wire of a desired length on a bobbin.

[Conventional technology]

Conventionally, there has been a wire winding device for winding a long supply wire onto another small bobbin to a desired length, for example, in order to use the long supply wire wound on a large bobbin as a reinforcing layer for a rubber hose or the like. The bobbin is supported between the spindles installed on the drive side and the driven side, and the winding point of the supplied wire is reciprocated in the axial direction by a traverser installed behind the winding position (with the forward direction of the supplied wire). 2. Description of the Related Art A wire winding device is known that moves to evenly wind a wire around a bobbin.

However, this wire winding device requires human labor to replace the bobbin and wind the wire after winding the wire onto the bobbin.

[Problem that the invention attempts to solve]

The present invention was devised in view of the above circumstances, and after winding the wire rod onto an empty bobbin is completed, the fully wound bobbin can be taken out from the winding position without the need for manpower, and the next step can be carried out. It is possible to easily supply an empty bobbin, and when the empty bobbin is transferred to a winding position without requiring manual labor and supported between a driving spindle and a driven spindle, it is possible to hold the supplied supply wire so that it can be wound. Therefore, the supply wire can be cut at the rear end of the fully wound bobbin, and the supply wire can be automatically wound around the next empty bobbin. in this way,
It is an object of the present invention to provide a wire winding device that can repeatedly perform a series of operations from replacing a bobbin to winding and winding a supplied wire and taking out a fully wound bobbin without requiring human labor. .

In order to achieve the above object, the present invention winds a wire from a wire supply source via a traverser onto a flanged bobbin that is installed at a winding position so that the winding center line is horizontal. The bobbin is supported at both ends by a drive spindle having a flange portion connected to a rotary drive device that is fitted into a center hole of the bobbin, and a driven spindle rotatably supported by a driven mechanism. In the wire winding device, the driven mechanism is coupled at one end of the arm,

An empty bobbin transfer device that can reciprocate in parallel with the winding center line, and a gripping mechanism that can grip the outer periphery of a fully wound bobbin after winding the wire to a predetermined length at the winding position. a fully wound bobbin transporting device having a gripping mechanism capable of transporting the fully wound bobbin from the winding position to the outside in the direction of an extension line connecting the traverser position and approximately the winding center; When the gripped fully wound bobbin is transferred outward from the winding position by the transfer means,
The supplied wire rod is pulled out together with the fully wound bobbin,
In this pulled out state, the pulled out wire is then pressed by the driven spindle swing drive device between the flange at one end of the empty bobbin to be mounted at the winding position and the flange provided on the drive spindle. The wire winding device is characterized in that it is equipped with a wire cutting device that cuts the drawn wire at a portion between the tip of the pressing holding portion and the fully wound bobbin.

[Effect]

Since the present invention is constructed as described above, at the winding position, the outer periphery of the fully wound bobbin after winding the wire rod onto the empty bobbin for a predetermined length is gripped by the gripping mechanism, and the gripped fully wound bobbin is The transfer means allows the wire rod to be transferred from the winding position outward in the direction of the extension line connecting the traverser and the winding center line at the shortest distance, and as a result, the wire drawn out together with the fully wound bobbin becomes empty at least at the winding position. It will cross the space in which the bobbin will be supported. Therefore, when an empty bobbin is gripped by its winding tube section by the empty bobbin transfer device, removed from the support rod, and transferred to the winding position parallel to the winding center line, a portion of the drawn wire is transferred to the drive spindle. It is held between the provided flange portion and the collar on one end side of this empty bobbin.

Next, by driving the driven spindle swing drive device, even if the gripping means is removed, the empty bobbin is fitted with the driven spindle in the center hole on the other end side, and is supported between the driven spindle and the driving spindle. At the same time, the idle bobbin is pushed toward the driving spindle by the driven spindle.

Therefore, the portion of the wire that is clamped between the flange provided on the drive spindle and the collar on one end of the empty bobbin is pressed and clamped.

The drawn wire is then cut by a wire cutting device at a portion between the tip of the pressing clamp and the fully wound bobbin.

When the wire is cut in this way, the tip of the wire remaining on the wire supply side is pressed and clamped between the flange provided on the drive spindle and the collar on one end of the empty bobbin. By driving the spindle, the empty bobbin rotates, and the supplied wire is guided by the traverser and automatically wound around the empty bobbin.
