Of the collapsible side plate 23a, and a fixing member 75 fixed to the collapsible side plate 23a of the winding drum 20 and rotatably fixing the intermediate portion of the coupling arm 74 via a shaft. The claw portion 71 is inserted into and taken out of the storage portion 21 of the winding drum 20 through the opening 26. Although the claw portion 71 is rotated in and out through the shaft, a cylinder 72 is provided along the winding shaft 22 in addition to the cylinder rod 73.
The claw portion 71 may be provided at the tip of the and the claw portion 73 may be slid toward and away from the winding shaft 22. or,
The locking means may be a chuck device 7 that is a fixing portion that presses the conduit tube P inserted in the groove 25, or may be a groove side wall that can fit and fix one end of the conduit tube P. That is, the locking means may be configured such that one end of the conduit tube P is sandwiched between both side walls of the groove 25 and fixed so as not to come off.

In the present invention, the collapsible side plate 23a is also provided.
The moving means is not limited to that of the embodiment using the cylinder 24 and the link mechanism 27, and a motor or the like may be used as the moving means. Further, in this embodiment, the collapsible side plate 23a falls in the take-out direction of the conduit tube P, so that the conduit tube P
However, in the present invention, the movement of the collapsible side plate 23a is limited only to fall if the fixation of the conduit P is released and there is no hindrance when removing the conduit P. Instead, for example, a cylinder is placed in the axial direction of the take-up drum 20, and the take-up shaft 22 is detached by the cylinder.
The collapsible side plate 23a fitted to the
The fixing of the conduit P to the winding drum 20 may be released at the same time when a is removed in the axial direction of the winding drum 20.

The replacement device 3 includes an arm 31 and an arm 31.
The belt 35 that is stretched over the rotating shaft 33 of the
And a motor 36 for rotating the arm 31 via the rotary shaft 33, and the winding drums 20 at both ends of the arm 31 are turned around the rotation shaft 33. In the embodiment, the arm 31 is fixed by the knock 32 when not inverted. Further, in the embodiment, the arm 31 is fixed in the state of descending to the right (FIG. 1).
That is, the empty winding drum 20 that winds the conduit is at a high position (left side in FIG. 1), and the winding drum 20 that has finished winding the conduit P is at a low position (right side in FIG. 1). As a result, after the arm 31 is reversed, the height of the conduit of the winding drum 20 that has finished winding the conduit and the groove 25 provided on the winding surface of the empty winding drum 20 for winding the conduit next. The height can be adjusted. Therefore, the conduit can be easily fitted into the groove 25 of the empty winding drum 20, and the next winding operation can be smoothly performed.

The tube pressing device 5 comprises a pressing plate 51 for pressing the electric wire tube wound on the winding drum 20 from the outside and a cylinder 52 for moving the pressing plate 51 up and down. When reversing, the pressing plate 51 is located above, and after the arm 31 is reversed, the pressing plate 51 descends,
It is adapted to be pressed against the outside of the electric wire tube wound on the winding drum 20. The tube holding device 5 is designed to prevent the electric wire tube wound around the winding drum 20 from loosening.

The tube cutting device 4 has a cutter 41 at its tip and is adapted to move forward and backward (vertical direction in FIG. 2) orthogonal to the winding drum 20 at the winding position. This tube cutting device 4 moves a winding drum 20 wound with a wire tube from a winding position to a bundling position, hangs the wire tube on the replaced empty winding drum 20, and takes up an empty winding wire. Drum 20
After the electric wire tube is locked by the locking means, the electric wire tube is activated to cut the electric wire tube.

Next, the operating state of this automatic winding machine will be described. First, the electric wire tube P is sent out from the extruder (not shown) between the rotating rolls 11 and 12 of the traverse device 1 and into the groove 25 of the housing portion 21 of the winding drum 20. At this time, the chuck device 7 is, as shown by the chain line in FIG.
The cylinder rod 73 pushes down the connecting arm 74 so that the claw portion 71 does not project from the surface of the collapsible side plate 23a. When the conduit P is inserted into the groove 25 in this state, the cylinder rod 73 pulls up the connecting arm 74, and the claw portion 71 presses the conduit P housed in the groove 25 from above. Thereby, the conduit P is securely fixed in the groove 25 of the winding drum 20.

When the conduit P is fixed, winding is started, and the chuck device 7 continues fixing the conduit P during this period. After winding the conduit P, the rotation of the winding drum 20 is stopped and the replacing device 3 is actuated, the knock 32 for fixing the arm 31 is disengaged, and both ends of the arm 31 are centered around the rotation shaft 33 of the arm 31. The take-up drum 20 is reversed.

The winding drum 20 on which the electric wire P has been wound moves to the binding position by reversing the arm 31. And
The outside of the conduit P is pressed by the pipe pressing device 5 so that the conduit P does not loosen. Further, the tube cutting device 4 operates to move the electric wire tube P to the winding start position of the winding drum 20 and cut the winding end. In this case, the groove 25 into which one end of the conduit tube P is inserted is the winding start position. The winding drum 20 that has moved to the winding position is also provided with the chuck device 7 having the same structure, and fixes the electric wire tube P that moves to the winding start position during this tube cutting operation.
Start the winding work.

The conduit tubes P which have been moved to the bundling position and cut by the tube cutting device 4 are bound at a predetermined position by the bundling device 6. The bundling device 6 is located at a bundling position for advancing (leftward in FIG. 1) at the time of bundling and bundling the bundle of electric wires P wound on the winding drum 20 and retracting after the bundling is completed (see FIG. 1).
(To the right), the arm 31 of the exchange device 3 can be inverted.

Next, the retractable side plate 23a of the winding drum 20.
However, by the operation of the cylinder 24, the cylinder 24 is tilted in the tube bundle removal direction via the link mechanism 27. Simultaneously with the fall of the collapsible side plate 23a, the claws 71 of the chuck device 7 come off in the tube bundle removal direction. As a result, the fixing of one end of the conduit tube P is released. When the one end of the conduit P is released,
Extrusion cylinder 8 provided behind the winding drum 20
With 0, the bundle of bundled electric wires P is pushed out toward the front. The tube bundle extruded in such a state is separately conveyed by a belt conveyor or the like.

[0020]

As described above in detail, in the automatic winder according to the present invention, the winding drum on which the tube is wound is replaced with the empty winding drum, and the empty winding drum is replaced. After the pipe is hung on the empty winding drum and the pipe is locked to the empty winding drum by the locking means, the pipe is cut and the replaced empty winding drum starts winding the next pipe. This makes it possible to continuously wind the tube. Therefore, the next winding operation cannot be performed unless the electric wire tube wound from the winding drum is removed, and the production efficiency is remarkably higher than that of the conventional winding machine in which one winding is required for each product. Can be realized,
Cost reduction and labor saving can be achieved.
