Abstract

PURPOSE:To aim at ensuring the set hooking of uncured tires and the unloading thereof at the next process step, by providing a tire set hooking device having a plurality of carriers and an inverted auxiliary guide, and a tire unloading device for automatically removing tires from hangers and feeding them to the next process step. CONSTITUTION:A bead section is shifted to a hanger H which is then advanced while stopper arms are closed, and a carrier 30C2 is advanced to that an uncured tire W is inverted. With the repetition of the above-mentioned steps to shift several tires W onto hangers H. When a tire W passes through a gap S between roller conveyers 61a, 61b in a tire unloading device 60, the tire W strikes upon the conveyers 61a, 61b, and stopper arms 62 which extend from and retract into the outer surfaces of the conveyers 61a, 61b are raised to push up the tire W from the hanger H. Then, after the forward end of the hanger H passing through the conveyers 61a, 61b, the stopper arms 62 are lowered to dump the tire W which is therefore delivered to the next process step. Thus, the tires W fed from a hanging conveyer 10 are shifted onto the hangers H one by one, and are automatically conveyed, while they are automatically unloaded from a tire unloading device 60, thereby it is possible to enhance the assurance of conveyance.

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

First, in FIG. 2, from a state in which the carrier 30C3 is stopped on the tire input conveyor device 31, a green tire W is input by the tire input conveyor device 31 to a position where the tire tread portion touches the fork 47.

Then, the drive motor 36 rotates, and the carrier 30C1
The carrier C4 is transferred to the feeding conveyor device 31.
Coming to the part.

Thereafter, the raw tires W are repeatedly stored in the carrier 30Cs. The number of carriers 30C1 to 30C6 is 5 in the figure.
However, the quantity is not limited. Chain guide 4
2.43 is the weight of raw tire W and carrier 30C1-30
Prevent C3 from sagging.

When storage of raw tires W is completed in each carrier 30C1 to 30C5 and an empty hanger H rotating on the trolley rail 11 arrives, the tire stopper arm 54, which had been open, is closed by a signal (as shown in FIG. 8), and the drive is driven. As the motor 36 rotates, the U-carved metal fitting 30a of the carrier 30C1 becomes approximately vertical in FIG.
Supported by 4.

The raw tire W rides on two forks, as shown in Fig. 2, centered in the left and right direction, and the hanger H can easily enter the center.

An empty hanger H enters into the tire bead W1, the tire stopper arm 54 opens, and the hanger H pushes the upper part of the green tire W in the traveling direction, making the green tire W slightly diagonal, and the bead part rides on the hanger H and is transferred. be done. The hanger H advances a little further, the stopper arm 54 closes, the carrier 30C2 advances, the green tire W is turned upside down, and the same process is repeated to transfer the green tire W to the hanger H. It is preferable to set the number of hangers H in the loft so that the maximum number of raw tires W that can be stored and transferred can be transferred.

The raw tires W transferred to the hanger H one after another in this way
When the green tire W passes through the gap S between the slide-shaped roller conveyors 612 and 61b of the green tire loading and unloading device 60 shown in FIGS.
1b, the stopper arm 62 that retracts from the surface of the roller conveyors 61a, 61b rises and pushes up the green tire W from the hanger H. After the tip of the hanger H passes the roller conveyors 61a, 61b, the stopper arm 62 descends. Then, the raw tires W are loaded and unloaded, and are sequentially transported to the process.

By the above-mentioned operation, the hunking conveyor device 1
The raw tires W sequentially supplied by the green tires W are transferred to the hanger H, are automatically transported, and are automatically unloaded from the raw tire loading/unloading device 60.

〔Effect of the invention〕

The present invention provides an endless hanger in which a plurality of hangers suspended so as to be rotatable and positionable as described above are driven around at a constant speed.

A plurality of carriers configured to support at least two surfaces of a green tire are provided on a gagging conveyor device and a chain that is installed below the hunking conveyor device and is driven in an endless rotation. A tire setting hanging device comprising an auxiliary guide mechanism and a green tire transported by the hanger,
Since it is constructed with a tire loading/unloading device that automatically removes the tires from the hanger and transports them to the next process, it has the following excellent effects.

(1) No elevating device is required, and the rails of the hunking conveyor device can be installed low.

(2) It is possible to reliably set and transfer green tires and unload them in the next process.

(3) It is reliable because the raw tires on the carrier are directly transferred to the hanger.
