Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a green tire molded by a tire molding machine,
The present invention relates to a raw tire handling device that can be automatically taken out from a raw tire forming drum and transferred to a carrier truck or the like.

(Prior Art) Tire forming machines for manufacturing automobile tires include those for bias tires and those for radial tires.

The bias tire molding machine is an endless laminating of tire constituent materials such as a carcass ply and a tread on a substantially cylindrical molding drum, and a molded raw tire is supported by a pedestal that can be moved up and down and moved, and then the drum. After the diameter is reduced, the pedestal is moved in the axial direction of the tire building drum to pull out the raw tire from the drum.

Further, the radial tire molding machine has primary and secondary molding, and the primary molding machine is an endless laminating of tire constituent materials such as carcass ply and bead wire on a substantially cylindrical molding drum. The green tire is taken out from the primary molding drum in the same manner as the case of the bias tire.

Further, the secondary molding machine fits and holds the bead portion of the primary green tire by the two bead holding disks that slide in the axial direction,
By pushing both bead holding disks close to each other while sending compressed air into the raw tire, the cylindrical raw tire is deformed into a toroidal shape, and then a belt or tread is endlessly attached to the outer peripheral portion and molded. The raw tires (hereinafter referred to as secondary raw tires) are supported by a pedestal that can be raised and lowered, and the bead holding plates are pulled out from the left and right bead portions of the raw tire to opposite sides.

Conventionally, as a device for taking out the secondary green tire molded by a secondary molding machine from a molding drum, there is one disclosed in JP-A-58-28364. That is, this take-out device mounts the vicinity of each bead portion of the primary green tire on a carriage that is movable in the axial direction of the secondary molding drum, and clamps the vicinity of each bead portion of the secondary green tire from both sides. The supporting members are arranged so as to face each other, and further, the supporting members can be moved equidistantly in opposite directions on the axis, and one of the supporting members can be swung with respect to the axis. It has become. The secondary green tire transferred on the dolly is mechanically carried out by an input or a hook.

Further, as a device for taking out and transporting the secondary green tire transferred on the cradle, there is one disclosed in Japanese Patent Publication No. 63-19333. This latter device includes a traveling frame that travels above the secondary tire molding machine along the overrail, and a slide that slides at a right angle to the traveling direction of the traveling frame along a guide shaft provided on the frame. It is composed of a moving frame and a suction means which is attached to the lower part of the sliding frame via an elevating means and is removably adsorbed to the upper surface of the secondary green tire on the pedestal.

(Problems to be Solved by the Invention) The former of the above-mentioned devices is capable of extracting a secondary green tire from a secondary molding machine, but the extracted secondary green tire must be carried out artificially or by a hook. Must
Transferring between a plurality of transfer devices is indispensable, it is difficult to avoid mechanical interference with other devices, etc., and operation time loss including the standby position of the transfer device cannot be eliminated, which is one of the factors that hinder productivity improvement. It becomes one.

In addition, the latter of the conventional devices has a problem in safety because the pedestal for the secondary green tire is indispensable and the suction means using the suction cup is adopted.

Therefore, under the present circumstances, there is a problem that the taking out of the secondary green tire and the loading on the carrier are dependent on the labor of the worker, the fatigue of the worker is large, and the productivity improvement is hindered.

The present invention has been made in view of the actual situation as described above,

Then, the traverse carriage 7 is retracted, and the raw tire gripping means 14 is moved to the raw tire.
When a predetermined position on the outer circumference of G ₂ is reached, the traverse carriage 7 is stopped, and when the raw tire gripping means 14 is closed to grip the raw tire G ₂ , the traverse carriage 7 advances again and the raw tire G ₂ becomes the tire forming drum 2a.

First, the transverse carriage 7 stands by at the position shown by the two-dot chain line 701 in FIG. 2, and the raw tire gripping means stops at the waiting position shown by the two-dot chain line 141 in FIG.

Therefore, when the primary green tire G ₁ is placed on the starting end of the conveyor 3 as shown in FIG. 2 and FIG.
Starts operation and the primary green tire G ₁ is transferred in the direction indicated by the arrow (a), the conveyor 3 itself also moves in the same direction (a), and stops at the position indicated by the chain double-dashed line 301 in FIG. To do.
At this time, since the raw tire gripping member 106 of the manipulator 4 is located on the end of the conveyor 3 in the open state, the primary raw tire G ₁ is inserted into the gripping member 106 and the gripping member 106 is contracted and closed.

Then, the traverse carriage 7 is retracted in the direction shown by the arrow (a) in FIG. 2, and the horizontal shaft 13 is driven by the raw tire gripping means drive motor 78.
By 90 degrees to make the finger 86 horizontal and make the secondary green tire G ₂ in a tilted state, and at the same time, the revolving structure drive motor.
When the revolving structure 12 is rotated by 90 degrees in the horizontal direction by the 68, the finger 86 is directed in the direction shown by the arrow (a) in FIG. 2, and when the secondary green tire G ₂ reaches the carriage 5, the proximity switch 30, the traverse drive motor 22 is stopped,
The transverse carriage 7 stops at a predetermined position.

In addition, the lifting motor 53 starts to drive the lifting body driving screw shaft.
49 rotates, the lifting body 10 descends, and the rotary encoder 52
Position is detected by the motor 53, the brake of the motor 53 is operated at a predetermined position, and the lifting body 10 is stopped.
Both fingers 86 are moved outward by the 87 to be expanded, and the secondary green tire G ₂ is transferred onto the carrier 5. In this manner, when the transfer of the secondary green tire G ₂ is completed, the lifting / lowering body 53 is slightly lifted by the lifting / lowering motor 53, and the finger 86 remains in the open state, while the green / tire-holding means driving motor is driven.
The revolving structure drive motor is turned 90 degrees by the 78 and becomes vertical.
The revolving structure 12 is turned 90 degrees by the 68 to be directed toward the secondary green tire molding machine 2 side, the vertical carriage 8 is stopped in front of the molding machine 2, and the raw tire gripping means 14 is shown in FIG. Dotted line 141
The standby position indicated by is reached.

By the above operation, fitted to the primary raw tire G ₁ of the secondary raw tire forming machine 2 of the drum 2a, taken out from the molding machine 2 of the secondary raw tire G _2, conveying, transferring to transport carriage 5 1 cycle is automatically performed.

In the above embodiment, the rotary encoders 35, 45 and 52 detect and stop the moving positions of the traverse carriage 7, the vertical carriage 8 and the lifting body 10, and the stop of the movement limit deteriorates the function of each motor-equipped brake device. In order to cover the above, safety is enhanced by the two-step control by the operation of the proximity switch. Further, the rotation of the revolving unit 12 and the shaft support block 82 is stopped by the combined use of the proximity switch and the stopper bolt, even if the braking function of each drive motor 68, 78 is lowered.
We are working to improve safety by ensuring a reliable stop. The above operation sequence can be changed as appropriate.
