Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a green tire setting/hanging device, and more specifically, a device for setting and hanging a green tire, and more specifically, a device for holding a molded green tire in a carrier provided on a chain that goes around it. The present invention relates to a green tire setting device for efficiently transporting green tires to the next process, which can efficiently transport the green tires without widening the interval between carriers and without deforming the green tires.

[Prior Art] Conventionally, methods for transporting shaped green tires to the vulcanization process include, for example, loading the green tires on a storage trolley and transporting them to the next process, and installing a hanger conveyor device on the shaping machine. A method for conveying raw tires by sequentially transferring them to the hangers of this hanger conveyor device (Japanese Patent Laid-Open No. 53-11298
Publication No. 0) etc. are known.

By the way, in the conventional transport method as described above, in the former case, a transporter is always required, and this transporter has to switch between the real trolley and the empty trolley, resulting in extremely low productivity. In addition, there was a problem in that unmanned transportation required a large amount of equipment cost.

In the latter case, it is necessary for a worker to hang each green tire on the hanger conveyor, which is not only inefficient but also dangerous.

Therefore, in order to solve the problem of the conventional device, the applicant of the present application proposed in Japanese Patent Application No. 59-133256 an endless hanger conveyor device that is equipped with a plurality of hangers and rotates at a constant speed. At the bottom of this hanger conveyor device, there is a chain conveyor equipped with a carrier for temporarily storing a plurality of raw tires, which is configured so that at least two sides of the raw tires can be supported on an endless chain, and this chain conveyor. A set hanging device is proposed, which includes a green tire gripping device and a lifting device, which grab the green tires on the carrier and move them up and sequentially transfer them to the hangers of the hanger conveyor device.

[Problem that the invention seeks to solve]

However, in the case of the above-mentioned set hanging device, there is a problem that the weight of the green tires causes the carriers to close up, and when the next green tire is loaded, the gap between the carriers becomes narrower, making it difficult to load the next green tire. There was also the problem that the shape of the green tire would be deformed.

[Purpose of the invention]

This invention was devised by focusing on such conventional problems, and it is possible to easily insert green tires into carriers without increasing the carrier spacing, and to effectively prevent green tires from deformation. The object of the present invention is to provide a set hanging device.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a plurality of carriers that are rotatably attached to a chain that goes around the base end portions of the carriers,
At the bottom of the carrier attached to the chain in the rotating direction,
A carrier holding means is provided for holding the green tire in the area from the green tire input position to the transfer device, and a carrier holding means is provided for suspending the carrier along the chain in the area from the transfer device to the green tire input position. The gist is that the chain is raised vertically in the green tire loading area, and the area from the green tire loading completion position to the transfer device is arranged so as to be inclined in the chain turning direction.

[Action of the invention]

This invention is constructed as described above, and the carrier is attached at a predetermined pitch to the circulating chain, and is attached so as to be inclined in the turning direction so that the side where the green tires are introduced is wider, and after the green tires are transferred, By hanging down along the chain, it is easy to insert the green tire, and the green tire is not deformed when it is introduced.

[Embodiments of the invention] Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 shows a front view of a green tire setting device according to the present invention, and FIG. 2 shows a side view of FIG. It is installed at the bottom of the hanger conveyor device 3.

The set hanging device 1 is attached to the upper and lower parts of an upright frame 4, and has a plurality of sprockets 5a, 5b, 5c,
Two chains 6a and 6b are hung around 5d and 5e,
The sprocket l-5e disposed on the lower side is configured to be rotationally driven by the drive motor 7.

In addition, the above two chains 6a. 6b rises vertically in the input area Z from the input bottom position A of the raw tire W to the upper input position B of the sprockets 1 and 5C, and also from the upper input position B to the position of the transfer device 8 for the raw tire W. In the region X up to this point, the raw tire W is arranged to be inclined so as to be held at a predetermined inclination angle α. Specifically, frame 4
The sprocket 5e attached to the lower part of the sprocket and the sprocket 5a attached to the upper part of the sprocket are horizontally shifted and attached, and the chain 6a, which is wound around the sprockets 5a and 5b,
6b is tilted 306 from the vertical position. Further, from the viewpoint of the deflection of the carrier 9 when the raw tire W is placed and the stability of the raw tire W, the angle is preferably about 5° to 30'.

The amount of vertical movement of the two chains 6a, 6b is approximately half a pitch of the carrier 9 from the bottom position A of the raw tire W.

As shown in FIGS. 2 to 4, on the two chains 6a and 6b, a plurality of carriers 9 on which green tires W are placed are rotatable about a rotation center ○ at a predetermined pitch. In this carrier 9, a U-shaped pipe 11 that supports the side surface of the green tire W is attached to a support plate IO that is attached in parallel to two chains 6a and 6b.

At the bottom of the carrier 9 attached to the chains 6a, 6b in the turning direction, as shown in FIG. In the area Z up to B, the raw tire W is kept in a horizontal state, and the raw tire W is
In the region X up to the position of the transfer device 8, there are provided carrier holding stages 12 that hold the green tires W at a predetermined inclination angle α.

Moreover, in the area Y from the raw tire W transfer device 8 to the input bottom position A, the carrier 9 hangs down along the chains 6a, 6b due to its own weight and is transported.

Therefore, the U-shaped pipe 1l always has chains 6a, 6
It is not in the state of extending outward from b, but hangs down along the chains 6a and 6b at least in the return process, that is, in the region Y from the transfer device 8 to the input bottom position A.
A large space is not required, and space can be saved.

Further, the transfer device 8 is installed on the upper part of the frame 4,
A clamp device 13 holds the outer peripheral surface of the green tire W transferred by the carrier 9 in a vertical state, and the clamp device 13 is raised along the guide rail 14 to the transfer position of the hanger conveyor device 3, and the hanger It is comprised of a lifting device 15 that transfers the green tires W onto the conveyor device 3.

The clamping device l3 is composed of a pair of clamp arms 17a and 17b that expand and contract using a cylinder 16, and clamps the raw tire W transferred by the carrier 9 vertically with its upper and lower outer peripheral surfaces. It is meant to be clamped.

The clamp device 13, the drive motor 7 that drives the chains 6a and 6b in rotation, and the lifting device 15 are electrically connected and interlocked by a detection means (not shown).

Next, the operation of this invention will be explained.

As shown in FIG. 5, in the area Z from the bottom position A of the raw tire W to the top position B of the sprocket 5c,
The two chains 6a and 6b rise vertically, and the carrier 9 is held horizontally, and the raw tire W is put in in this area Z. At this time, the leading carrier 9 is From the upper input position B, the carrier 9 is attached to chains 6a and 6b having a predetermined inclination angle α.
Therefore, the distance between the carrier 9 at the input position iA and the carrier 9 at the position B after loading becomes wider on the green tire input side, as shown in FIG.

Therefore, when the raw tire W is put in, the carrier 9 that precedes the
It can be easily thrown in without colliding with other objects. When the green tire W is held on the carrier 9 in an inclined state, as shown in FIG.
However, since the loading side of the raw tire W between the carriers 9 is widened in advance, the raw tire W can be easily loaded without deforming the raw tire W as described above.

In this way, the carrier 9 on which the raw tire W is placed is
By the rotational drive of the chains 6a and 6b, the chain is generally fed to the position of the transfer device 8, and then the clamp attachment M1 of the transfer device 8 is moved.
3, the green tire W is lifted along the guide rail 14 by the lifting device 15, and transferred to the hanger conveyor device 3 to be conveyed to the next process.

The carrier 9 from which the green tire W has been taken out by the transfer device 8 enters the return area Y by the chains 6a and 6b, and at this time, the carrier 9 moves along the two chains 6a and 6b by its own weight with the center of rotation O as the fulcrum. The tire is rotated to a vertical state, and in this state, it is transported again to the loading position A of the green tire W.

Furthermore, when the hanging carrier 9 comes close to the raw tire W loading position A, it rises again from the two chains 6a, 6b due to its own weight, becomes approximately horizontal, and enters the raw tire W loading receiving state. Become.

With the above operations, the raw tires W can be easily loaded into the carrier 9 without deforming them, and after the raw tires W have been transferred, the carrier 9 hangs down along the chains 6a and 6b, thus saving a large space. Loading work can be easily performed without removing the carriers 9 or increasing the spacing between the carriers 9.

〔Effect of the invention〕

As described above, the base end portions of a plurality of carriers are rotatably attached to a chain circulating around the base end portions of the carriers, and a transfer device is provided at a lower portion of the carrier attached to the chain in a rotating direction, from a loading position for green tires to a transfer device. In the area, the green tires are held, and in the area from the transfer device to the green tire loading position,
A carrier holding means for suspending the carrier along the chain is provided, the chain is vertical in the green tire loading area, and the area from the green tire loading completion position to the transfer device is inclined in the chain rotation direction. Since the arrangement is such that green tires can be easily loaded into the carriers without increasing the carrier spacing, deformation of green tires can be effectively prevented. After completion, the carrier hangs down along the chain, so it is possible to save space without taking up a lot of space.
