Description

[Detailed description of the invention] Birth-upper 1 The present invention relates to a transport device for tire constituent members.

Conventionally, a cylindrical tire is attached to a second forming drum of a second forming machine that extends from a first forming drum of a first forming machine in the same direction as the first forming drum and is coaxial with the first forming drum. As a conveying device for conveying the structural members, one example is known, such as the one described in Japanese Patent Publication No. 82-35381. This thing has a horizontal rail installed on one side of the first I&-shaped drum and the second forming drum so as to straddle them, and is movably supported by this rail, and is located between the first forming drum and the second forming drum. The tire is equipped with a movable trolley, and a gripping means that is movably supported by the trolley and capable of gripping a cylindrical tire component from the outside.

Then, using such a device, the tire component is first
When transporting the tire component from the forming tram to the second forming drum, the tire component of the first forming drum is gripped by the gripping means, and then the truck and the gripping means are moved along the rail to transfer the tire component to the second forming drum. 1. Pull out from the forming drum.Next, raise the grip stage that grips the tire component, and then lift it to the stage. i1 Grasping gripping means Tire component physically moves along the rail to the side of the second forming tram 6
Next, the tire component and the gripping means are lowered until the tire component and the second forming tram are coaxial.
Move the truck along the rail and move the tire components to the second
The conveyance is completed by transferring it to the forming drum.

However, in such a device for transporting tire components, it is necessary to suspend the rails from the ceiling or support them by erecting supports from the floor, which makes the entire device large and difficult. There is a problem that the rails are expensive, and a further problem is that such rails generally get in the way of the beams of the overhead running lanes that are provided for size switching and the like. Furthermore, since it is necessary to raise and lower the tire component and the grip stage each time it is transported, there is also the problem that energy consumption is large. Generally speaking, as the molding speed increases, the first. Even though the molding cycle time of the second molding drum is shortened, the entire process from the first molding drum to the second molding drum is carried out while being gripped by a single gripping means.
The cycle time of the conveyance is the same as the first one. There is also the problem that the molding cycle time becomes longer than the molding cycle time of the second molding drum, and as a result, the cycle time of the entire molding apparatus becomes longer and the working efficiency decreases.

An object of the present invention is to provide a tire component conveying device that is compact and inexpensive as a whole, does not interfere with other devices, can further save energy, and can improve work efficiency. With the goal.

Such an object is to provide a first forming machine with a first forming drum extending forward from a first drive and having a horizontal axis, and a second drive disposed behind said first forming machine. A second molding machine is provided near a second molding machine having a second molding drum that extends forward from the part and is coaxial with the first molding drum, and the cylindrical tire component is transferred from the first molding drum to the second molding drum.

This can be achieved by providing a rotating gripping mechanism that can be used.

When transporting a cylindrical tire component from the first forming drum to the second forming drum, first move the gripper in the axial direction of the first forming drum in a horizontal plane until it becomes coaxial with the first forming drum. Next, the moving body and the gripping body are moved together in the axial direction of the first forming drum, and the gripping body is moved to the outside of the first I&-shaped drum. here,
Since the axis of the first forming drum is horizontal, the gripping body moves in a horizontal plane.Next, after the gripping body grips the tire component on the forming drum from the outside, the moving table and the tire The gripping body that grips the component is moved in the opposite axial direction to the above and separated from the first forming drum.Next, the gripping body is moved in a direction perpendicular to the axial direction of the first forming drum, and the first forming Move to one side where there will be no interference with the drum. Next, the moving platform and the gripping body that grips the tire component are moved together in the axial direction of the first forming drum, and the tire is moved to the outside of the rotating gripping mechanism that is waiting at the first position coaxial with the gripping body. Transport components. next,
The tire component is transferred from the gripping body to the rotating gripping mechanism.

At this time, the rotating gripping mechanism grips the tire component from the inside. Next, rotate the rotating gripping mechanism 180 degrees,
It is moved from the first position to a second position coaxial with the 22nd holding mechanism. Next, the 2822nd feeding mechanism is moved in the axial direction to the outside of the swing gripping mechanism while maintaining a coaxial relationship with the second forming drum. Here, the axis of the second forming drum is coaxial with the 11th &-shaped drum and is a water mold.

The second transport mechanism will move in a horizontal plane.

Next, the tire component is transferred from the rotating gripping mechanism to the second conveyance mechanism. After moving to the outside of the forming drum, the tire component held by the second conveyance mechanism is transferred to the second forming drum, and from the first forming drum to the second forming drum as follows. The tire component is transported, and here, the first
Since the moving table, gripping body, and second transport mechanism that make up the transport mechanism always move within the water surface, there is no need for large-scale rails, making the entire device smaller and cheaper to manufacture. It also saves energy and does not interfere with other equipment, such as crane beams. In addition, in this invention, the 11th I! Since the two feed mechanisms and the second conveyance mechanism are sequentially provided and the conveyance path is divided into two, the conveyance cycle time of each conveyance mechanism can be shortened compared to the case where the entire process is conveyed by the gripping means of the second stand. Ta. As a result, the transport cycle time is reduced to 1. The molding cycle time can be made close to, or even less than, the molding cycle time of the second molding drum, thereby shortening the overall cycle time and improving work efficiency. In addition, if tire components can be temporarily stored in the rotating gripping mechanism disposed between the 1st and 2nd conveyance mechanisms, it is possible to prevent the lag in molding timing between the 1st and 21st molding drums. It can also be absorbed.

Next, the operation of one embodiment of the present invention will be explained.

First, the first driving unit 2 of the first molding machine 1 rotates the first molding drum 3 whose diameter is expanded, and the first JA
The inner liner and carcass ply are successively pasted around the shaped drum 3 to form a cylindrical tire component, that is, the green case G. Next, the green case Gt is formed.
- Convey from the first forming drum 3 to the second forming drum 8. In this case, first actuate the loftless cylinder 40 of the first conveying ljk bridge 11 to move the gripping body 38 to the first forming drum in a horizontal plane. It is moved in the direction perpendicular to the axial direction of No. 3, here toward the other side. The movement of the gripping body 38 is stopped when the center of the circle passing through the holders 34, 35 and the axis of the first forming drum 3 become coaxial. At this time, each of the first gripping arms 30 and 31 is located at the lower limit, and operates the air motor 21 to run the chain 24 at the 0th order which is farthest from each other, and moves the moving base 18 and the gripping body 38 integrally. It is moved axially rearward to approach the first forming tram 3. Here, since the axis of the first forming drum 3 is horizontal, the gripping body 38 always moves within a horizontal plane. and a holder 34 of one gripping body 38.
35 reaches the outside of the green case G on the first forming drum 3, the operation of the rodless cylinder 40 is stopped.
Then, the axial movement of the moving base 18 and the gripping body 38 is stopped.
1 are lowered and raised by equal distances, respectively, to approach fL. As a result, the eleven blocks 36,37 of the holder 34,35 come into contact with the outer periphery of the green case G. Then, with these buffer blocks 38.37 in contact with the outer periphery of the green case G, a brake is applied to the cylinder to position and fix the gripping arm 30.3I at the position, and the green case G is held from the outside by the gripping body 38. grasp. In this state, the diameter of the first forming drum 3 is reduced, and the green case G is transferred from the first forming drum 3 to the gripper 38.

Next, the air motor 21 is operated to run the chain 24, and the gripping body 38 holding the moving table 1B and the green case G is moved axially rearward of the first forming drum 3 in a horizontal plane. Separate from 3. When the gripping body 38 of the moving table 181 moves to the forward limit, the operation of the F motor 21 is stopped, and then the rodless cylinder 40 is activated to move the gripping body 38 in the axial direction of the first forming drum 3 within the water f plane. , in the direction perpendicular to , in this case, to the − side. As a result, the green case G gripped by the first gripper 38 retreats to a position where it does not interfere with the first molding machine l, and the gripper 38 is moved back to the first position a.
It becomes coaxial with the inner grip body 7B waiting at A.

On the other hand, the first +& type drum 3 from which the green case G was taken out.
Immediately after this removal, the molding of the green case G is restarted. Next, the air motor 21 is activated to move the chain 24.
When the moving platform 18 and the green case G are moved, the gripping body 38 that grips the moving table 18 and the green case G moves axially backward in a horizontal plane and approaches the rotating gripping mechanism 71 while passing one side of the first molding machine l. do. When the green case G gripped by the first gripper 38 is conveyed to the outside of the inner gripper 76, the operation of the air motor 21 is stopped.

Next, the piston rod 89 of the cylinder 87 of the rotating gripping mechanism 71 is made to protrude. As a result, the link 84°85,
1 gripping segment 83 is swung so that 88 gradually stands up.
moves outward and expands in diameter. And this cylinder 87
The piston rod 88 stops protruding when the gripping segment 83 comes into contact with the inner circumference of the green case G. After releasing the brake of the cylinder of the gripping body 38 in this state,
The cylinders are actuated to move the gripping arms 30.31 up and down, respectively, and remove the holders 34.35 from the green case G. As a result, the green case G that has been gripped from the outside by the gripper 38 is gripped from the inside by the inner gripper 76 of the rotational gripping mechanism 71, and the rotary actuator is actuated to rotate the rotation shaft 74. The arm 75 and the inner gripping body 76 that grips the green case G are integrally moved from the first position ilA to the second position around the pivot shaft 74.
Rotate 180 degrees in the horizontal plane toward position IB.

At the end of this rotation, the inner grip 76 reaches the second device B, and the axis of the inner grip 76 and the axis of the second transport mechanism 47 become coaxial. At this time, the moving table 18 and the gripping body 38
moves forward in the axial direction and returns to the initial position.

Next, actuate the cylinder 68 and its piston rod 69
is retracted, and the second transport mechanism 47 is moved along the rail 46 to the second transport mechanism 47.
The molding drum 8 is moved forward in the axial direction.

Here, since the axis of the second forming drum 8 is coaxial with the first forming drum 3 and is horizontal, the second conveying mechanism 47 moves within the surface of the water 7. The movement of the second conveyance mechanism 47 is stopped when the second conveyance mechanism 47 is fitted to the outside of the inner grip body 7B located in the second device B. 64 and rotate the cam ring 51 of the second transport mechanism 47 clockwise in FIG. As a result, all movable plates 58,
The gripping segments 57 synchronously move radially inward while being guided by the guide rails 54. The radially inward movement stops when the gripping segment 57 comes into contact with the outer periphery of the green case G.Next, the piston rod 83 of the cylinder 87 of the rotating gripping mechanism 71 is retracted to reduce the diameter of the gripping segment 83. let As a result, the green case G is moved from the rotation gripping mechanism 71 to the second transport mechanism 47.
and is gripped from the outside by the second transport mechanism 47.

Next, the piston rod 68 of the cylinder 68 is projected to move the green case G and the second transport mechanism 47 axially rearward within the water surface. This second transport mechanism 47
The movement of the green case G stops when it is aligned with the outside of the second forming drum 8. At this time, the rotating gripping mechanism 71 rotates 180 degrees in the opposite direction to that described above and returns to the initial position.
Next, after expanding the diameter of the second forming drum 8 and gripping the green case G from the inside, the cylinder 63 of the second conveying mechanism 47
The piston rod 64 of is retracted to expand the diameter of the gripping segment 57.

The green case G is transferred from the second transport mechanism 47 to the second forming drum 8. Next, after returning the second transport mechanism 47 to the initial position, the green case G is transferred to the second forming drum 8. While deforming it into a toroidal shape, the belt/tread assembly is transported to the outside of the green case G and pasted together to form a green tire.
Next, the green tire formed in this way is
It is taken out from the r& shaped drum 8 and conveyed to the next process.

As described above, the second forming drum 8 hegelin case G is conveyed from the first forming drum 3.

Here, a moving table that constitutes the first transport mechanism 11! 8, the gripping body 38, and the second transport mechanism 47 move within the plane of the tree, so there is no need for rails, which are large-scale equipment, and:
! The entire 4i installation is miniaturized and can be manufactured at low cost, and furthermore, it does not interfere with other equipment 1, such as a crane beam. In addition, since the first conveyance mechanism 11 and the second conveyance mechanism 47 were sequentially provided on the conveyance path of the green case G from the first forming drum 3 to the second forming drum 8, and the conveyance path was divided into two, each conveyance mechanism 11 The conveyance cycle time of .47 can be reduced compared to the case where the entire process is conveyed by one gripping means. As a result, the transport cycle time is reduced to 1. The molding cycle time can be made closer to or less than the molding cycle time of the second molding drum 3.8, thereby shortening the overall cycle time and improving work efficiency. Also, these first. If the green case G is temporarily stored in the rotating gripping mechanism 71 disposed between the second forming drums 3 and 8, the forming timing between the first +& shaped drum 3 and the second forming drum 8 may be misaligned. Even if there is, it can be absorbed.

In addition, although the above explanation focuses on one green case G and explains the operation of the molding machine and the conveying device, in reality, at the same time as the green case G is molded in the first molding drum 3, the first green case G is molded.
