Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an annular member winding device for spirally winding a belt-like wrapping member around an annular member such as a tire tube along the circumferential surface of the annular member in a small radius direction. In particular, the present invention relates to an improvement in the rotational drive mechanism of the annular member in the circumferential direction.

Conventionally, as a winding device for winding a band-shaped wrapping paper in a spiral shape around a small radius around an annular member made of a relatively hard part such as a coil of wire material such as a tire or an electric wire, or a steel band coil, the winding device was developed by Tokko Sho. Devices such as No. 36-22999 are known.

In such conventional winding devices, the target annular member is made of a relatively hard member, so the mechanism for rotating the annular member in the circumferential direction is
It is composed of a plurality of rotating rollers arranged on the side surface of an annular member, and the annular member is rotated while being held and supported at several points on the circumferential surface of the annular member so that the annular member does not swing during rotation.

However, when it is necessary to wrap a band-like member around the circumference of an inflated tire tube, for example, a reinforcing band-like member is wrapped around the circumference of the inflated tire tube, and then liquid rubber is integrated around this circumference. When molding and manufacturing a tire with an integral tube, since the inflated tire tube is flexible, the structure of conventional equipment in which the sides of the annular member are held and rotated by rollers makes it difficult for the tire tube to rotate. It deforms and cannot be rotated smoothly in the circumferential direction, and on the other hand, if the clamping force is loosened, it slips and cannot be rotated smoothly.

Therefore, it has been desired to develop a device that can smoothly rotate a flexible annular member such as a pneumatic tire tube in the circumferential direction and that can spirally wind a wrapping member around the annular member.

SUMMARY OF THE INVENTION An object of the present invention is to provide a winding device for an annular member that is capable of winding even a flexible annular member with a winding member made of paper tape or the like.

The present invention provides a circumferential rotation drive mechanism for an annular member with a drive roller that is in contact with the outermost circumferential surface of the annular member and supports the annular member from below, and a drive roller that is in contact with the outermost circumferential surface of the annular member and supports the annular member from above. and at least two guide rollers arranged along the circumferential direction of the annular member for pressing toward the drive roller side, and these at least two guide rollers are all driven by a vertical motion drive source. The guide roller is integrally movable up and down, thereby making it possible to attach and detach the annular member, and also to rotate the annular member while pressing and supporting it in an approximately radial direction, thereby achieving the above object. be.

It is designed to be rotated. Further, a core shaft 6 is erected on the side surface of the flyer 3, and a winding member 7 in the form of an elongated strip is wound around the core shaft 6.

A friction roller 8 is brought into contact with at least one of the rubber rollers 4, which is the rubber roller 4 at the lowest position in FIG.
is connected to a large motor 12 via chain transmission mechanisms 9, 10 and 11, and is rotated by this motor 12. Also, this motor 1
2 is fixed on the base 1.

A power distribution board 13 and an operation panel 14 are provided on the front surface of the fryer pedestal 2, so that each part can be operated. Further, a pair of drive mechanism pedestals 15 and 16 are provided on both rear sides of the flyer pedestal 2 (see FIG. 2), and a gear box 17 is provided behind the pair of pedestals 15 and 16. A small motor 18 is provided on the upper part of this gearbox 17, and the output shaft of this motor 18 is connected to the chain transmission mechanism 1.
A worm (not shown) connected to the input shaft 20 of the gearbox 17 through the input shaft 9 and attached to the inner end of the input shaft 20 is located behind the flyer holder 2 in FIG. The output shaft 21 is rotated by meshing with a worm wheel (not shown) attached to the inner end of an output shaft 24 rotatably supported on the pedestal 15 via a bearing box (not shown). It's becoming like that.

Two large and small sprockets 22 and 23 are fixed in the middle of the output shaft 21, and a sprocket 25 is connected to the larger sprocket 22 via a chain 24, and this sprocket 25 is connected to the fryer holder 2. The drive roller 26 is integrally fixed to a drive roller 26 with a flange that is rotatably supported by the output shaft 21, and the drive roller 26 is rotated as the output shaft 21 rotates. Also, the sprocket 2 is connected to the smaller sprocket 23 via a chain 27.
8 are connected, and this sprocket 28 is connected to the frame 29
is rotatably supported. A gear 30 is attached to this sprocket 28 so that it can rotate integrally,
This gear 30 has a gear 3 fixed to a rotating shaft 31.
2 are engaged. This rotary shaft 31 is rotatably supported by a bearing box 33 provided on the other pedestal 16, and a flange having the same shape as the drive roller 26 is attached to a protrusion of the shaft 31 from the bearing box 33. The drive roller 34 is fixed, and the output shaft 21
It is designed to rotate as the . Further, the two drive rollers 26 and 34 cause an annular member 35 such as a pneumatic tire tube to
The lower part of the shaft is supported on its outermost circumferential surface and is rotatably driven in the circumferential direction.

A support stand 36 in the form of a front gate is erected on the fryer pedestal 2, and a cylinder 37 as a vertical movement drive source is erected at the upper end of this support 36 with a piston rod 38 facing downward. . Two guide rollers 40 are rotatably supported at the lower end of the piston rod 38 via a connecting plate 39, and these guide rollers 40 are formed in the shape of a drum with a concave center. 2
They are provided at symmetrical positions in the figure, and are able to come into contact with the outermost peripheral surface of the annular member 35. Further, a pair of guide bars 42 are connected to the lower end of the piston rod 38 via a horizontal plate 41, and these guide bars 42 are erected vertically and attached to a bush 43 fixed to the support base 36. These guide bars 42 and bushes 43 allow the piston rod 38, connecting plate 39, and guide roller 40 to move up and down in a straight line without rotating. At this time, the stroke of the piston rod 38 is such that each guide roller 40 moves toward the annular member 35 at the most advanced position.
on the other hand, in the most retracted position, each guide roller 40 presses the annular member 35 slightly downward.
The annular member 35 is positioned sufficiently away from the upper surface of the drive rollers 26 and 34 so that the annular member 35 can be inserted into or taken out from the drive rollers 26 and 34.

Note that the interlocking mechanism from the small motor 18 to the rotating shaft 31 via the output shaft 21, the drive rollers 26 and 34 driven by this interlocking mechanism, and the two guide rollers 40 provide a rotational drive mechanism for the annular member 35 in the circumferential direction. is configured.

Next, the operation of this embodiment will be explained.

The cylinder 37 is actuated to raise the piston rod 38 and both guide rollers 40 to be raised. In this state, the annular member 35 is inserted between the flanges of the lower drive rollers 26 and 34, and the cylinder 37
are driven in opposite directions so that both guide rollers 40 press the annular member 35 slightly against the drive rollers 26 and 34. At this time, the pressing force of the annular member 35 by the guide roller 40 is such that the annular member 35 does not deform significantly and the drive rollers 26, 34
The value is set to a value that allows sufficient rotational drive. Furthermore, when inserting the annular member 35,
As shown in FIG. 1, the cutout portion of the flyer 3 is positioned upward so as not to become an obstacle to the insertion of the annular member 35.

Next, the outer end of the winding member 7, which has been previously wound around the core shaft 6 of the fryer 3, is fixed to a predetermined location on the annular member 35, and the large motor 12 and small motor 18 are driven. As a result, the flyer 3 and each drive roller 26, 34 are driven, and the drive of the drive rollers 26, 34 causes the annular member 35 to smoothly rotate in the circumferential direction of the large radius. Therefore, the winding member 7 is wound helically around the small radius circumferential surface of the annular member 35 by the flyer 3 rotating in a plane that intersects the rotation plane of the annular member 35. .

After the wrapping member 7 is wound around the entire circumference of the annular member 35 in this way, each motor 12, 18
At the same time, the cylinder 37 is operated to raise the guide roller 40, the annular member 35 is taken out, and the winding of the annular member 35 is continued in the same manner.

At this time, by appropriately adjusting the rotational speed of each motor 12, 18, the degree to which the spirals of the wrapping member 7 overlap can be adjusted as desired.

According to this embodiment as described above, the annular member 35
The rotation of the flanged drive rollers 26, 34
Since this is done using two guide rollers 40 that can come into contact with and separate from the annular member 35, the annular member 35 can smoothly rotate even a flexible member such as a pneumatic tire tube without flattening it. Moreover, not only flexible members but also general hard members can be smoothly rotated. Furthermore, since the piston rod 38 of the cylinder 37 as a vertical movement drive source is guided vertically up and down without rotating by a pair of guide bars 42, the two guide rolls 40 and the annular member 35 Proper contact can be maintained at all times. moreover,
Each guide roll 40 is shaped like a drum with a concave center,
Moreover, since the driving rollers 26 and 34 are flanged, it is possible to effectively prevent the annular member 35 from falling off during the winding operation. Further, since two guide rolls 40 are provided, the contact with the annular member 35 is reliable, and from this point as well, it is possible to effectively prevent the guide rolls from falling off.

In addition, in implementation, the drive rollers 26, 34 and the guide rollers 40 are not limited to two each, but may be three or more, but two of each may be sufficient. It is the most advantageous in terms of cost. Furthermore, if a stop collar or the like is provided on the protrusion of the guide bar 42 from the upper surface of the support base 36, and the mounting position of this collar is adjustable, the stroke of the cylinder 37 can be easily adjusted, and the annular member 35 can have different diameters. It can be easily adapted to other things. Furthermore, if the cylinder 37 is provided with a speed controller that controls the supply speed of the pressure fluid or a damping mechanism such as a tension spring between the support base 36 and the connecting plate 39, the contact between the guide roller 40 and the annular member 35 can be improved. The contact can be made gentle, and impact on the annular member 35 can be avoided.

As described above, according to the present invention, there is an effect that it is possible to provide a winding device for an annular member that can easily wind even a flexible annular member using a winding member.
