Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for introducing a tip end of a tire member in a tire molding machine.

[0002]

2. Description of the Related Art Conventionally, all work has been done manually.

[0003]

The above-mentioned prior art has the following problems. (1) All the work is manual and inefficient. (2) If the work of introducing a wide sheet material (width of 500 mm or more) onto the introduction conveyor is done manually, if it is done from one side of the let-off device or the introduction conveyor, the far side cannot be reached. Therefore, there is a problem that the tire member is introduced to the front side while being distorted, and in order to avoid this, two or more people must work.

It is an object of the present invention to provide an automatic introduction device capable of mechanically introducing the tip of a tire member.

[0005]

[Means for Solving the Problems] The following members or mechanisms are installed. (1) Move the tire member to the introduction conveyor by holding the tip of the tire member outside the introduction conveyor and moving it to the center of the introduction conveyor, and moving it in the running direction of the introduction conveyor while pressing the tip of the tire member against the introduction conveyor. Introducing roller. (2) A latch mechanism that is attached to a reciprocating frame that supports an introduction roller, is connected to a truck for unwinding tire members, and inserts the truck for unwinding tire members into a let-off device. (3) A sensor that detects the position of the tip of the tire member, and a mechanism that drives the trolley for unwinding the tire member to the position at the center of the introduction conveyor.

[0006]

Operation: The tip end of the tire member unwound from the tire member unreeling carriage is transferred to the introduction conveyor via the introduction roller. Further, the tire member is aligned with the center line of the introducing conveyor by a sensor, an introducing roller device, or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. 2 and 3 conceptually show the entire servicer for a tire molding machine equipped with the automatic tip introducing device for a tire member according to the present invention. The tire forming machine servicer is disposed behind the tire forming drum 1 and introduces a tire member unreeling carriage 2 that conveys a tire member and unwinds it in the servicer, a let-off device 3 that drives unwinding, and a tire member. Introducing conveyor 4, tire forming drum 1
It is composed of a sticking conveyor 4'for supplying a tire member to the tire.

In FIG. 1, a is a material that is unwound from the tire member unrolling trolley 2 and is composed of a tire member b and a liner c. 6 is an introducing roller device, 7 is a latch mechanism, 8 is an introducing conveyor, 9 is a tire member detecting sensor, 10 is a rail, 11 is a reciprocating frame, 12 is a rail, 13 is an introducing roller base, 14 is an introducing roller, 15
Is an air cylinder, 16 is an introduction roller arm, 18 is a holder, 19 is a notch, 20 is a latch, and 2a and 2b are stock rolls and unwinding parts of the truck 2 for unwinding tire members.

In the introducing roller device 6, a reciprocating frame 11 is suspended on a rail 10 which is installed on a servicer frame (not shown), and the frame 11 is parallel to the axis of the stock roll 2a and located at the center position of the introducing conveyor. It is possible to reciprocate between and the position on the insertion side of the truck for unwinding the tire member by a driving device (not shown). Further, an introducing roller base 13 which is movable in the center line direction of the introducing conveyor by a driving device (not shown) is suspended on the rail 12 of the reciprocating frame 11. An introduction roller 14 is swingably attached to the introduction roller base 13 by an air cylinder 15, and a holder 18 is swingably attached to the introduction roller arm 16 so as to press the surface of the introduction roller. A latch 20 is attached to one end of the reciprocating frame 11 so that it can be connected to a notch 19 provided in the frame of the tire member unwinding truck 2 shown in FIGS. There is.

A sensor 9 for detecting the widthwise position of the tire member b is installed at the inlet of the introduction conveyor, and the tire member is unwound by a driving method (not shown) which is normally performed by a signal from the sensor 9. The cart 2 controls the axial position of the stock roll 2a. Next, the operation of this device will be described. (1) Preparation The tire member unwinding carriage 2 and the introducing roller device 6 are set at the position shown in FIG. 2B, and the tip of the tire member b is wound around the introducing roller 14 as shown in FIG. 1C. It is held by the holder 18.

The following operations are automatically performed. (2) The latch 20 is connected to the notch 19, and the reciprocating frame 11 is moved toward the center of the introducing conveyor 8 until the let-off device 3 and the drive shaft of the tire member unwinding carriage 2 are connected (position A in FIG. 2). The tire member unwinding carriage 2 moves while maintaining the relative position of the introduction roller 14.

After the driving force of the reciprocating frame 11 is cut off to be free, the operation of the sensor 9 is started. After that, the tire member b is constantly controlled to a predetermined position of the introduction conveyor 8 by the operation of the sensor 9. (3) The introduction roller 14 is pressed against the introduction conveyor 8 by the air cylinder drive (position D in FIG. 1), and the holder 18
Is released, the introduction roller base 13 is driven in the direction of the introduction conveyor center line, and the tip of the tire member is transferred to the introduction conveyor 8 (position E in FIG. 1).

The latch 20 is released from the notch 19. (4) The introduction conveyor 8 is driven to feed the tire member. The unwinding of the tire member is controlled by a commonly used method. At this point, the introduction roller 14 may be kept pressed against the introduction conveyor 8 as a pinch roller, or may be separated from the introduction conveyor 8 if unnecessary. (5) After the tire member is unrolled, the latch 20 is connected to the notch 19 and the reciprocating frame 11 is driven to drive the tire member unrolling carriage 2 and the introduction roller device 6
To the preparation position (position B in FIG. 2).

Even if the centering sensor 9 and the drive device for the stock member 2a of the tire member supply truck 2 in the axial direction are not provided, the function of automatically introducing the tip of the tire member is achieved.
