DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, all operations are performed manually.

[0003]

The above-mentioned prior art has the following problems. (1) All work is manual work and efficiency is poor. (2) When introducing a wide sheet material (500 mm or more in width) onto the introduction conveyor by hand, if it is done from one side of the let-off device and the introduction conveyor, human reach does not reach the far side. Therefore, there is a problem that the tire member is introduced while being distorted to the near side, and in order to avoid this, it is necessary to work by two or more people.

An object of the present invention is 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) The tire member is moved to the introduction conveyor by holding the tip of the tire member outside the introduction conveyor, moving to the center of the introduction conveyor, and moving the tire member in the traveling direction of the introduction conveyor while pressing the tip of the tire member against the introduction conveyor. Introducing roller. (2) A latch mechanism attached to the reciprocating frame supporting the introduction roller, connected to the tire member unwinding cart, and inserting the tire member unwinding cart into the let-off device. (3) A sensor for detecting the position of the tip of the tire member, and a mechanism for driving the truck for unwinding the tire member to a position at the center of the introduction conveyor.

[0006]

The leading end of the tire member unwound from the tire member unwinding cart is transferred to the introduction conveyor via the introduction roller. Further, the tire member is centered on the center line of the introduction conveyor by a sensor, an introduction roller device, or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIGS. 2 and 3 conceptually show the entirety of a servicer for a tire forming machine equipped with the automatic device for introducing a tip of a tire member according to the present invention. The servicer for a tire forming machine is disposed behind the tire building drum 1 and transports a tire member and unwinds the tire member in the servicer. A truck 2 for unwinding, a let-off device 3 for driving unwinding, and a tire member are introduced. Conveyor 4, tire building drum 1
It is composed of a sticking conveyor 4 'for supplying tire members to the conveyor.

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

In the introduction roller device 6, a reciprocating frame 11 is hung on a rail 10 provided on a servicer frame (not shown), and the frame 11 is positioned parallel to the axis of the stock roll 2a and at the center of the introduction conveyor. It can be reciprocated by a drive device (not shown) between the tire member unwinding cart and the insertion side position of the tire member unwinding cart. An introduction roller base 13 is suspended from a rail 12 of the reciprocating frame 11 by a driving device (not shown) in the direction of the introduction conveyor center line. An introduction roller 14 is attached to the introduction roller base 13 so as to be swingable by an air cylinder 15, and a holder 18 is attached to the introduction roller arm 16 so as to be able to swing so as to press the introduction roller surface. A latch 20 is attached to one end of the reciprocating frame 11 so as to be connectable to a notch 19 provided on the frame of the tire member unwinding cart 2 shown in FIGS. I have.

A sensor 9 for detecting the position of the tire member b in the width direction is installed at the entrance of the introduction conveyor. The position of the cart 2 in the axial direction of the stock roll 2a is controlled. Next, the operation of the present apparatus will be described. (1) Preparation The tire member unwinding cart 2 and the introduction roller device 6 are set at the position shown in FIG. 2B, and the tip of the tire member b is wound around the introduction roller 14 as shown in FIG. It is held by the holder 18.

The following operation is automatically performed. (2) Until the latch 20 is connected to the notch 19 and the reciprocating frame 11 is connected to the introduction conveyor 8 in the center direction, the let-off device 3 and the drive shaft of the tire member unwinding cart 2 are connected (position A in FIG. 2). It moves while maintaining the relative position between the tire member unwinding cart 2 and the introduction roller 14.

[0012] After the driving force of the reciprocating frame 11 is cut off freely, the operation of the sensor 9 is started. Thereafter, the tire member b is constantly controlled to a predetermined position on the introduction conveyor 8 by the operation of the sensor 9. (3) The introduction roller 14 is pressed against the introduction conveyor 8 by driving the air cylinder (D position 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 moved 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 send out the tire members. The unwinding of the tire member is controlled in the usual manner. 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 unwinding of the tire member is completed, the latch 20 is connected to the notch 19 and the reciprocating frame 11 is driven, so that the unwinding truck 2 for the tire member and the introducing roller device 6 are driven.
To the preparatory position (position B in FIG. 2).

The function of automatically introducing the tip of the tire member can be achieved even when there is no centering sensor 9 and no drive device for the axial direction of the stock roll 2a of the tire member supply cart 2.

[0015]

According to the present invention, there is provided an apparatus for automatically introducing a tip of a tire member, comprising: a let-off device for a tire member; an introduction conveyor;
In a device for introducing the tip of a tire member from a tire member unwinding trolley to a tire forming machine servicer composed of a sticking conveyor or the like, a reciprocating motion is performed between the unwinding part of the tire unwinding trolley and the introduction part of the introducing conveyor. An introduction roller base, an introduction roller supported swingably up and down by the introduction roller base, and a holder for temporarily holding the tip of a tire member on the introduction roller. By transferring the tip of the tire member from the unwinding part of the unwinding cart to the introduction part of the introduction conveyor, the tip of the tire member is automatically transferred from the unwinding cart of the tire member without human intervention. Can be introduced into a tire molding machine.
