Abstract

PURPOSE:To make easy the takeout operation of a flipper and to improve the sticking operation of a flipper, by feeding automatically the tip of the flipper to the inner circumferential surface of a tire bead, and cutting automatically it. CONSTITUTION:A flipper (f) fed through between a support plate 100 and a tire bead is turned about 90 deg. by a turning guide roll 322, and while the tip of the flipper (f) is guided by a guide plate 323, it is clamped by clamping claws 326 of a flipper clamping mechanism 324. In this state, a cutter cylinder 380 of a flipper cutter mechanism 324 is caused to perform the contraction and expansion operation so that the tip of the flipper (f) is cut diagonally. The tip of the cut flipper (f) is pressed against the inner surface of the tire bead in position via a press roll 325 by the contraction and expansion operation of a pressing cylinder 375.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a flipper in a tire bead manufacturing device.
The present invention relates to a feeding device, and more specifically, to a novel flipper feeding device that automatically feeds a flipper to the back side of a bead and automatically cuts the flipper to a specified length at a predetermined position.

Conventionally, this type of device includes a support plate (not shown) installed vertically, as shown in FIGS. 1 and 2, for example.
The vinyl support supplies the tire bead W formed into a circular shape in another processing step to the guide roller 1 via a bead supply device (not shown), and the bead support supplies the tire bead W to the guide roller 1 and the filler guide unit. At the same time, on the surface of this bead W, the bead receiver holds a filler pressure bonding roll 2 and a filler advance guide 3, which are disposed above the guide roller 1 and can be moved up and down. Filler F is supplied through the tire bead W, and a bead receiver is provided on the inner surface of the tire bead W by a guide roller 1.
The flipper f is supplied through a flipper supply device 4 disposed at the bottom of the tire bead W, and the filler F and flipper f are simultaneously supplied through a forming roll 5 disposed on the rotationally moving side of the tire bead W. I was wearing it.

However, in such a conventional device, since the bead receiver of the support plate carries the tire bead W into and out of the guide roller 1 linearly from its axial direction, it is difficult to form the bead to which the flipper f is attached. The roll 5 itself was a hindrance, making it difficult to automatically supply and remove the tire bead W.

Moreover, even if a tire bead W loading/unloading device is made that avoids the forming roll 5, it will still be a device mortar.

The feeding operation of the tire bead W becomes complicated and the number of man-hours increases, which increases the price of the equipment, and it takes a lot of time and effort to put in and take out the tire bead W. In the end, the actual production process relies on manual labor. I had no choice.

Further, as shown in FIG. 2, since the tip F1 of the filler F and the tip of the flipper fl are simultaneously attached to the bead W from the same position via the detection means 7, the tip of the filler F is attached to the bead W from the same position at the same time. There is a problem in that the tip end is crushed or the filler cutter 6 cuts up to the tip of the flipper f, resulting in errors such as shortcomings.

Furthermore, a conventional filler cutter 6 and a flipper cutter (
In the cutter (not shown), the filler F and the flipper f were both cut using a gun type, and as a result, the cutter itself had to have a strong structure, which resulted in a large space occupied by the cutter itself.

This invention was devised by focusing on the conventional problems, and its purpose is to advance the flipper and automatically bring the tip of the flipper onto the inner peripheral surface of the tire bead. Automatically cutting as well as feeding makes it easy to carry in and out of the printer, while significantly improving the workability of attaching the flipper. Also, by making the flipper cutter mechanism more compact, the space occupied by the entire device is reduced. The present invention provides a flipper supply device in a tire bead manufacturing apparatus that can perform the following steps.

In order to achieve the above-mentioned object, the present invention includes a support plate provided on a support plate, in which a guide roller and a bead guide are rotatably disposed in the bead receiver, and above the bead receiver kite roller, a filler pressure bonding roll and a filler pressure bonding roll are arranged. A filler guide unit including a cutter and a filler guide is disposed so as to be movable up and down, and the bead receiver is provided with marimbar attached to the inner surface of the bead below the guide roller and on the entry side of the bead of the filler pressure roll. A flipper supplying device is provided, and the bead receiver is provided with a forming roll device on the bead moving side of the guide roller, above the rotation locus of the tire bead, and at a position that does not interfere with the tire bead feeding direction. A flipper abutting mechanism which is movably disposed, guides the tip of the flipper to the inner circumferential surface of the tire bead, and clamps the tip of the friso/'S-. The gist of this is that it is composed of a flipper-clamp mechanism and a flipper-cutter mechanism that cuts the tip of the tire bead clamped by the flipper-clamp mechanism.

There is.

Next, the operation of the present invention constructed as described above will be explained.

First, as shown in FIG. 27, the bead receiver is attached to the guide roller 1.
The tire bead W, which has been clamped vertically by the fingers x1 of the heat supply device X, is transferred to 41.

That is, when finger x 1 comes to position 31 in FIG.
Contact at T1 position of 31,132, and further finger x 1
When the tire bead W reaches the bead release position S2, the tire bead W is pulled upward by 4 degrees, and the lower end of the lower heat receiver is raised to the T2 position of the guide roller 13L132, and as shown in FIG. 13L 132 and the third forming roll 431 of the forming roll device 400.

Here, as the finger x1 of the bead supply device X is opened, the tire bead W slides on the inclined support plate 100, and the bead receiver fits into the a140 of the guide roller 141 and is supported.

When the bead W supply operation is completed in this way, the third
As shown in FIG. 4, the filler guide unit 20
0 is operated to lower the frame 220 for unit installation, and the unit installation is performed by the filler pressure bonding roll 260 mounted on the frame 220.
Filler Kaido Unisol l-230. The filler cassock device 250 is used to lower and position the filler F in order to apply it to the tire bead W. At the same time, the first forming roll 417 and the second forming roll 426 of the forming roll device 400 are moved to the respective first cylinders 411.
It swings in a direction perpendicular to the rotational direction of the tire bead W via the second cylinder 421, and clamps the tire bead W from both sides thereof.

On the other hand, the bead tension roll 136
35, and the bead receiver is lowered by the guide roller 141.
This applies a predetermined tension to the tire bead W supported by the tire bead W.

The tension is adjusted by vertically adjusting the position adjustment lever 137 and adjusting the stroke of the cylinder 135. Further, in the flipper supply device 300, the pressing is performed by the flipper butting mechanism 320 by the cylinder 375.
swings upward, and the presser roll 325 shown in FIGS. 18 and 19 presses the tip f1 of the flipper f against the inner peripheral surface of the tire bead W, thereby adhering the tire heat W to the inner peripheral surface rubber layer. Do the following.

With the above steps, preparations for bonding the filler F and the flipper f are completed, and as the drive motor 142 (not shown in FIG. The rotational driving force is applied to the filler press roll 260 through the moving shaft 148.263. The bead receiver is a guide roller 141. transmitted to the third forming roll mechanism 430,
Tire bead W is rotated while attaching filler F and flipper f to tire bead WG.

The pressure is applied to cylinder 3 at the same time as the rotation of the tire bead W starts.
75 lowers the free-shoulder abutting mechanism 320, and
As shown in FIG. 8 and FIG. 19, the flipper-f is
The flipper vines 379 are prepared by positioning the flipper f in the operating plane of the flipper cutter 379 without applying extra tension to the flipper f since the flaps become straight.

As shown in FIG. 29, the filler F and the flipper-f are such that the tip F1 of the filler F is pasted to the inner peripheral surface of the tire bead W before the tip f1 of the flipper-f, and the tire bead It is detected by a detection means 600 such as a phototube for detecting the tip of the filler disposed near the rotation locus G of W.

When the tip F1 of the filler F is detected by the detection means 600, at the same time, the drive motor 142 stops driving the rotary shaft 1, and the rotation of the tire bead W is stopped. Here, the filler cutter 251 is moved down by the cank cylinder 253,
Cut filler F at position kl. At this point, the tip F1 of the filler F has stopped at a position where it just abuts the end F2 of the filler F after cutting.

On the other hand, the flipper-f is different from the case where the filler F is advanced and the tip IFI of the filler F and the non-JP2 are exactly matched. Therefore, the tire bead W has to be rotated that much more. Therefore, after the filler cutter 251 returns to its original state, the drive motor 142 makes a small rotation again and rotates the tire bead W to the cutting position 2 of the flipper-f. With this small rotation, the cut end F2 of the filler F and the filler F in a floating state between the filler pressure bonding roll 260 are pressure-bonded to the tire bead W by the filler pressure bonding roll 260, and the tip F1 and the end F2 of the filler F are It is pressure bonded.

After the drive motor 142 stops rotating in this manner, the flipper cutter 251 is operated by the cutter cylinder 380 to cut the flipper f, and at the same time, the lifting cylinder 210 raises the filler guide unit 200 to remove the filler. Flipper-f by pressure roll 260
This is to prevent the crushing of the material.

After cutting the flipper f, the end f of the flipper 1 is moved to form the unformed flipper between the forming roll device 400 and the flipper cutter 379.
2 passes through the forming roll mechanism 400.
42 rotates to rotate the tire bead W.

After tire bead pulling is completed in this way, the drive motor 142 is stopped, and the tension roll 136 is raised by the cylinder 135 to release the tension on the tire bead W, and the first forming roll 417. The second forming roll 426, the first cylinder 411. Second cylinder 42
1 and rises.

Next, between the supply of the tire bead W and the end of the final rotation of the bead, the completed tire is transferred to the bead loading finger (see FIG. 26) of the handling device 700 waiting in front of the tire bead manufacturing device according to the present invention. Bead W1
The kick-out claw 520 is moved to the kick-out cylinder 540 in order to pass the receiver.
rotates around the pin 530, and the tire bead W
is kicked out from the tire bead manufacturing device and transferred to the handling device 700.

Furthermore, when the kicking pawl 520 returns and the handling device 700 carries away the tire bead W, the insertion of the tire bead W into the receiving LJ for pasting the next filler F and flipper r is completed, and the above-mentioned operation is repeated. be.

By incorporating the bead kicking device 500 into the tire bead manufacturing device itself, the tire bead W can be taken out at the same time the processing is completed in the flipper supply device 300 and other processing machines, and the next tire bead W can be removed.
As described above, it is possible for the supply device to clamp and wait for supply, which has the advantage of shortening the cycle time.

As described above, the bead receiver has a guide roller and a bead guide rotatably disposed on the support plate provided on the support, and the bead receiver has a filler pressure bonding roll, a filler cutter and a bead guide above the guide roller. A filler guide unit equipped with a filler guide is arranged to be able to move up and down, and the bead receiver has a flipper attached to the inner surface of the bead below the guide roller and on the entry side of the bead of the filler pressure bonding roll. A flipper supply device is installed,

A flipper-butting mechanism that guides and butts the tip of the flipper to the inner peripheral surface of the tire bead, a flipper-clamp mechanism that clamps the tip of the flipper, and cuts the tip of the tire bead clamped by the flipper clamp mechanism. Since it is constructed with a flipper cutter mechanism, the tip of the flipper is automatically supplied to the inner circumferential surface of the tire bead and cut automatically without advancing the flipper, making it possible to easily insert and remove the flipper. At the same time, it has the effect of significantly improving the workability of attaching the flipper, and by making the flipper cutter mechanism more compact, the space occupied by the entire device can be reduced. It also improves cutting of the filler and flipper and significantly extends the life of the cutter.

This has the effect of reducing the space occupied by the entire stretching device.

Furthermore, since each structure itself is relatively simple, it can be manufactured at low cost and maintenance is easy.
