And is driven by motors 8a and 8b (FIG. 6) in the main body 1 of the winder.

Further, the swivel frame 5 is driven by a motor 8 (Fig. 6) to rotate 180 degrees.
After turning once, it stops, and moves the winding bobbin 3 in the full winding state from the winding position A to the extracting position B, and at the same time, moves the winding bobbin 3 in the empty state to the reverse.

Further, in the line-drawing piece 9 protruding from both sides of the central portion of the swivel frame 5 between the two winding bobbins 3, 3, the winding bobbin 3 in the fully wound state swung from the winding position A to the withdrawing position B. At this time, it is a floating rotating piece having a conical slope and a collar for sliding the trailing line W ₀ to a clamp opening (described later) along the inner surface of the bobbin collar.

By providing the wire introduction portion 2 at a high position on the front surface of the winder main body 1 and then arranging the winding position A and the withdrawing position B side by side obliquely downward, the winding position A is fully wound. When the rotation drive of the take-up bobbin 3 is stopped and the take-up bobbin 3 is rotated in the direction of the arrow to the take-out position B, the succeeding linear wire W ₀ is between the introduction section 2, the linear drawing sesame 9, and the outer circumference of the wound wire bundle W. It is stretched in a tensioned state, and the succeeding filament W ₀ passes through the clamp position C and the cutting position D of the winding bobbin 3 in the empty state.

The cutting device 10 that advances to the cutting position D is briefly illustrated in FIGS. 2 and 3, which is a known mechanism.

Next, the clamp mechanism at the clamp position C will be described with reference to FIGS. 4 and 5.

FIG. 4 shows a state in which the succeeding filament W ₀ of the winding bobbin 3 in the fully wound state, which has been rotated to the extraction position B in FIG. 1, is cut by the cutting device 10 at the cutting position D.

Incidentally, umbilical clamp portion 11 of the winding bobbin 3 to clamp the trailing filament W ₀ before cutting is the major feature of this invention is described in the description of the winding bobbin 3.

As shown in FIGS. 4 and 5, the winding bobbin 3 is not fitted directly to the bobbin drive shaft 7, but fitted and fixed via the shaft cylinder 7a with the piston portion 7b.

Then, the fixed flange 12 fitted and fixed to the shaft cylinder 7a and the shaft cylinder 7a
Both ends of the take-up bobbin 3 are constituted by an undulating collar 14 composed of six collar members 14a which are supported by a ring body 13 fitted in the base end and radially extend.

The bobbin winding cylinder between the fixed collar 12 and the undulating collar 14 is formed of six winding body members 16 which are curved plate pieces fixed to each link member 15 for undulating each collar member 14a of the undulating collar 14. ing.

Then, as shown in FIG. 4, when the winding drum members 16 are aligned on the same cylindrical surface, a winding drum including a cut is formed, and the filament can be wound without any trouble.

Further, the fixed flange 12 is provided with the same number of radial slits 12 'communicating with each cut between the winding drum members 16, the outer end of each slit 12' is opened to the outer periphery of the fixed flange 12, and the inner end portion is formed. Reaches closer to the outer circumference of the ring body 13 than the winding barrel member 16.

Similar to FIG. 4, the upper half of FIG. 5 shows a cross section in a state where the undulating collar 14 is upright (when wound), and the lower half of FIG. 5 is a state in which the undulating collar 14 is laid down (extracted). Time).

When the mechanism for undulating the undulating collar 14 moves the ring body 13 sliding along the shaft cylinder 7a from the position depicted in the upper half of FIG. 5 to the position depicted in the lower half, the ring body 13 is moved. Each shaft support bracket 13a of each of the collar members 1 standing at right angles to the shaft cylinder 7a.

Further, since one end of the link member 15 is engaged with the base member 14a slightly above the base end thereof, and the other end of the link member 15 is engaged with the outer bracket 17 of the fixed flange 12, the flange member 14a is the fifth member. The winding barrel member 16 which is laid down like the lower half of the figure and fixed to the link member 15 is sunk inward like the lower half of FIG.

Therefore, a gap is formed between the inner surface of the fixed collar 12 and the end surface of the winding drum member 16.

Further, when the collar member 14a is raised, the open mouth is closed.

In this way, the portion where the mouth is opened when the up and down flange 14 is laid down and is narrowed, and the mouth is closed when the collar is returned is used as the linear clamp portion 11 of the winding bobbin 3.

In addition, the wire clamp 11 is not the end surface of the winding drum member 16,
It may be provided at the end of the link material 15.

Next, a mechanism for sliding the ring body 13 fitted in the shaft cylinder 7a keyed to the bobbin drive shaft 7 in the axial direction will be described with reference to FIGS.
It will be described with reference to the drawings.

A piston portion 7b is bulged at an intermediate position on the outer periphery of the shaft cylinder 7a, and the inside of the ring body 13 sliding on the outer periphery of the shaft cylinder 7a has a piston portion.
It is a cylinder inner wall 13b that makes 7b airtightly slide.

That is, the ring body 13 functions as a fluid pressure cylinder and slides in the axial direction when fluid pressure is applied before or after the piston portion 7b.

 18 and 19 are fluid inlets and outlets, and 20 is a fluid hose.

Explaining the fluid pressure circuit in FIG. 6, the fluid from the fluid pressure source is a fluid hose 20, a solenoid valve 21, a rotary joint 22.
Through the flow path in the swivel drive shaft 5a, exit from the flow path in the swivel drive shaft 5a, and by the left and right rotary joints 23, enter the internal flow path of the bobbin drive shaft 7 of the two bobbins 3, 3. An off-axis fluid hose 20 supplies the fluid to the fluid inlets 18 and 19 of the ring body 13 which is a cylinder from a position close to the winding bobbin 3.

In this state, the binding band is fed out along the rail, and when the tip makes one round, the rear part is pulled back, the midway of the binding band is pulled out from the U groove of the rail and tightened around the filament bundle W, and heat is applied to the binding part as is well known. Automatic fusing is performed by fusing.

Next, the winding bobbin 3 is rotated by the motor 8b, and the wire bundle W
Similarly, the other side is automatically bound.

Then, the ring body 13 of the winding bobbin 3 in the fully wound state is moved by the fluid pressure in the direction in which the up and down flange 14 is narrowed, and the bundled wire bundle W is moved by an unillustrated ejecting device as shown in FIG. Then, it is pushed down onto the conveyor 30 and sent to the product storage area.

Although one embodiment of the present invention has been described above, it is natural that the change and application according to the factory and the product can be made by the well-known technology of the designer and the site engineer who carry out the invention without changing the gist of the invention. .

<Effects of the Invention> As described above, according to the present invention, the mechanism for undulating the undulating collar, the wire end from the winding start of the wire until the wound wire bundle is removed from the winding drum member. Since the mechanism for clamping is made to work with one mechanism, it is possible to prevent the line from loosening or coming off from the beginning to the end of winding, and the drive mechanism becomes one to simplify the structure. It can be manufactured at low cost.

Further, since the drive mechanism described above is configured by the cylinder shaft having the piston portion fitted and fixed to the bobbin drive shaft and the ring body surrounding the outer periphery of the piston portion, it projects outside the winding bobbin and interferes with the work. Since there are no obstacles or obstacles, work becomes easier and safety is improved.

Therefore, it is possible to obtain a wire winding bobbin suitable for the automatic winding and binding device.
