Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a winding machine for winding a linear body on a bobbin (also called a drum), in which a rotational driving force is transmitted from the winding machine to the bobbin. The present invention relates to a kelipin for a winder.

[Conventional technology]

As shown in FIGS. 6 and 7, the bobbin has different sizes. The large bobbin 20 shown in FIG. 6 has a large-diameter collar 21 and its shaft hole diameter 22 is also large. Small bobbin in Figure 7
23 has a collar 24 with a small diameter, and its shaft hole diameter 25 is also small. However, as for the buttonholes 26 and 27 into which the buttonholes are inserted in order to transmit the rotational driving force from the winder to the bobbin, the hole diameter D1 and the central diameter D2 with respect to the center of the bobbin are usually set.
Is common.

The main part of the winding machine, on which such large and small bobbins are mounted, will be described with reference to FIG. The driven side flange 30 and the drive side flange 31 are arranged to face each other, and a table 32 which can be raised and lowered below the driven side flange 31
Are arranged. The driven side flange 30 is rotatably supported and is axially movable back and forth by a cylinder device 33. The drive side flange 31 is rotatably supported and positively rotated by the drive device 34. Then, in order to cope with the case where the bobbin shaft hole diameters are different, the driven side flange 30 and the drive side flange 31 are provided with a bobbin mounting cone (having a slight taper) matching the bobbin shaft hole diameter. And 2 small cones 36 (some have 3 or more)
Even if the diameters of the shaft holes 22 and 25 of the bobbins 20 and 23 are different, the bobbin mounting cone does not have to be replaced in correspondence with the bobbin shaft holes 22 and 25. Further, the button pin 37 is fastened to the outer peripheral portion of the driving side flange 31 with the nut 38, the button pin 37 engages with the button hole 26 of the bobbin 20, and the rotational driving force of the driving side flange 31 is transmitted to the bobbin 20 (bobbin 20). Only 20 is shown).

As shown in FIG. 5, when the bobbin 20 is mounted on the winder, an empty bobbin is placed on the table 32, and the table 32 is moved until the center of the bobbin shaft hole 22 and the center of the large diameter cone 35 are on the same line. And the driven side flange (not shown) is advanced in the axial direction by the cylinder device, and when the bobbin shaft hole 22 is slightly caught by the drive side cone 35, the advance of the cylinder device is once stopped. Then, the bobbin 20 is manually rotated until the position of the button hole 26 of the bobbin 20 is aligned with the button pin 37 fastened to the driving side flange, and the cylinder device is operated again to move the bobbin.
Attach 20 to large diameter cone 35. In this case, the bobbin shaft hole 22 is slightly (about 5 mm) in the large diameter cone 35 of the drive side flange 31.
When inserting, the collar 21 of the bobbin 20 is designed not to hit the tip of the button pin 37. Therefore, in the case of the bobbin 23 mounted on the small-diameter cone 36 shown in FIG. 4, the long hook pin 39 shown by the chain double-dashed line is used. That is, the short bobbin 37 is used for the bobbin 20 mounted on the large-diameter cone 35, and the long bobbin 39 is used for the bobbin 23 mounted on the small-diameter cone 36. ,
I replaced it with kelipin 37, 39 which matched 25.

[Problems to be solved]

However, in the above-described winding device, it is necessary to replace the button pin each time the bobbin shaft hole diameter changes. That is, it is necessary to remove the nut and fasten a new button pin, which causes a problem of poor workability in bobbin mounting.

An object of the present invention is to solve the above-mentioned problems of the prior art. A kelipin for a winder that can easily align the kelipin position corresponding to the cone to be used among the cones of the driving side flange is provided. It is intended to be provided.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the kelipin for a winder according to the present invention comprises a driven side flange and a drive side flange which are axially movable back and forth, and each flange is provided with two or more cones having different outer diameters. In a winder in which bobbins having different axial hole diameters can be mounted on the cone, and the key pin provided on the driving side flange engages the key hole of the pobin, the key pin is columnar, and the column key pin is Is formed in the hole of the drive side flange into which is inserted, the both ends of the groove are closed, and the end of the groove on the side opposite to the bobbin is bent in the circumferential direction, and the groove is provided on the circumference of the button pin. The hook pin is slidable and the spring which biases in the bobbin direction allows the hook pin to project in the axial direction so that the hook pin can be locked at both ends of the groove.

[Action]

In the present invention configured as described above, in order to make the keripin length that fits the cone to be used among the cones of two or more stages on the driving side flange, when the bobbin shaft hole diameter is small, the urging force of the spring causes the protrusion of the kerlipin. Is positioned so as to contact the end of the groove on the bobbin side, and if the bobbin shaft hole diameter is large, the protrusion of the button pin slides in the groove against the urging force of the spring, and further rotates in the circumferential direction. The protrusion of the button pin is locked to the bent portion of the groove by the biasing force and positioned.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of a Keripin for a winder, FIG. 2 is a view showing a groove in which a protrusion slides, and FIG. 3 is a cross-sectional view taken along the line AA of FIG.

In FIG. 1, the Keri-pin 1 has a columnar shape, a protrusion 2 is provided on the circumferential portion thereof, and a spring chamber 3 is bored at one end thereof. The drive side flange 31 is formed with a through hole 4 in which the button pin 1 slides, and a groove 5 in which the protrusion 2 slides and moves. One end of the groove 5 is closed by a lid 6 and the other end is closed by a cap 7. A blind hole 8 having the same diameter as the through hole 4 is provided in the cap 7, and a spring 9 is housed in the blind hole 8 and the spring chamber 3. Usually kelipin 1
Is in the solid line position by the biasing force of the spring 9. The kick pin 1 can be slid rightward against the biasing force of the spring 9 and can be pushed to the position indicated by the chain double-dashed line.

The shape of the groove 5 along which the protrusion 2 slides will be described with reference to FIGS. 2 and 3. The groove 5 indicates the width and depth with which the protrusion 2 is guided, and both ends thereof are closed by a lid 6 and a cap 7. Further, the groove end portion of the groove 5 on the side opposite to the bobbin is a bent portion 10 that is bent about 90 ° in the circumferential direction (the bending direction is opposite to the rotating direction at the time of winding the bobbin). The bent portion 10 has a width through which the protrusion 2 passes, and a burr 11 is provided at the entrance thereof so that the bent portion 10 is bent.
Stablely locked inside 10, from the bent part 10 of the groove during winding,
The stem 2 cannot come off.

Next, the operation of the kelipin for the winder having the above-described structure
It will be described with reference to the drawings. When the protrusion 2 of the hook pin 1 is locked to the bent portion 10 of the groove 5, the hook pin is located at the short position of the chain double-dashed line. Therefore, the large bobbin 20 shown in FIG. 4 can be mounted and engaged with the buttonhole 26. Then, when removing the protrusion 2 of the button pin 1 from the bent portion 10 of the groove 5, the button pin 1 is pushed once to escape from the burr 11.
When it is rotated in the circumferential direction, the locking of the groove 5 at the bent portion 10 is released, and the protrusion 2 of the button pin 1 slides until it comes into contact with the end surface of the lid body 6 by the urging force of the spring 8. Therefore, the small bobbin 23 shown in FIG. 4 can be mounted and engaged with the buttonhole 27. Furthermore, when the button pin 1 is returned to the position indicated by the chain double-dashed line, the button pin 1 is slid until the protrusion 2 of the button pin 1 comes into contact with the cap 7 against the biasing force of the spring 8, and the button pin 1 is rotated in the circumferential direction. Then, the protrusion 2 crosses over the burr 11 and is locked in the bent portion 10 of the groove 5. In this way, when the bobbin shaft hole diameter changes, the button pin 1 can be lengthened or shortened simply by sliding and rotating the button pin 1, and workability when the bobbin shaft hole diameter changes is improved.

Although the above-mentioned Keripin for the winder has a two-stage cone, for example, in the case of a three-stage cone, a bent portion that bends in the circumferential direction in the middle of the groove is added, or The second bent portion may be a combination of the bent portion, the subsequent axial groove, and the second bent portion.

[Effect of device]

The winding pin for a winder according to the present invention has a cylindrical column, and an axial groove is formed in a hole of a driving side flange into which the column pin is inserted, and both ends of the groove are closed, and an anti-bobbin is formed. The end of the groove on the side is bent in the circumferential direction, a protrusion provided on the circumference of the button is slid in the groove, and a spring biasing the bobbin allows the button to project in the axial direction. If the bobbin shaft hole diameter is small, the bobbin shaft hole diameter is small. The button pin slides in the groove against the biasing force of the spring, further rotates in the circumferential direction, and the button pin can be locked to the bent portion of the groove by the biasing force of the spring to position it. Easily buttoned corresponding to the cone to be used It can match down position, the work of the bobbin mounting is improved.
