Description

Extruding rubber control apparatus of radial tire

The present invention relates to a device for conveying and conveying the rubber extrudates produced through various extruders to the molding machine in the manufacture of radial tires for passenger cars, in particular the material of the rubber extrudate that can occur when the extrusion equipment is stopped by the continuous movement of the rubber extrudates supplied The present invention relates to an extrudate storage and conveying apparatus for a radial tire for a passenger car, which can prevent deformation and supply high quality rubber extrudates to a molding machine.

As is well known, in the molding process of tires, all components of the tires are sequentially pasted in a molding machine to form a cylindrical green tire, that is, the rubber extrusions of various semi-finished products are applied to a molding machine for making a tire shape. In another process, an extruder was prepared in advance and moved to a molding machine, which is a post process by using a carrier of a bogie or roll type, and then these semi-finished product extrudates were fed to a molding machine to make green tires.

Among the semifinished products conventionally supplied, rubber extrudates through an extruder are divided into extrudates having a predetermined shape (for example, tire tread or sidewall) and extrudates (for example, inner liner) supplied in sheet form. The rubber extrudate is loaded on a trolley or roll for loading and moving in the manufacturing process, and then passes through the standby state for storage according to the production plan, and then the extrudate is supplied to the molding machine.

This extrudate supply structure can be a model suitable for large production plants, but it is not desirable for small-scale production because the space and investment cost is large.

Therefore, the small-scale production plant eliminates the intermediate process of moving the extrudate and adopts only the rubber extrudate from the extruder and directly supplies it to the molding machine, thus eliminating the port, facility investment, and warehouse necessary for loading and moving the rubber extrudate. One facility can be configured.

However, conventional extruded moving equipment is a line concept equipment, which requires absolutely investment cost and space, and produces excess rubber extruded product than required in accordance with production plan. After storage for a certain period of time, it must be reprocessed or disposed of, and the area required by the increase and storage of various kinds of transport equipment has increased.

Therefore, the present invention was invented to solve the conventional problems as described above, and removes a series of processes, such as storage, moving, etc. required in the middle of feeding the rubber extrudates directly extruded from the extruder to the molding machine, rubber extruded products Passenger car that can supply high-quality extrudates while preventing the deformation of the material by not only supplying to the molding machine while maintaining this constant speed but also storing and supplying the extrudate even when the equipment is stopped due to the trouble of the surrounding equipment. It is an object of the present invention to provide an apparatus for storing and conveying extrudates of radial tires.

The present invention for achieving the above object is an extruder conveying apparatus of a radial tire for a passenger car for supplying the rubber extrudates supplied from the extruder to the supply conveyor of the molding machine, the rolls between the extruder and the supply conveyor of the molding machine The first and second storage loop conveyors are spaced apart from each other, and the first and second storage loop conveyors are connected to each other by a frame, and are configured to adjust the increase and decrease of the extrudate while being moved up and down according to the operation of the sensors.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram showing an operating state of the extrudate storage and transport apparatus of a radial tire for a passenger car according to the present invention.

The present invention is an extruder conveying apparatus of a radial tire for a passenger car for supplying a rubber material extrudates (2) supplied from an extruder (1) to a supply conveyor (3) of a molding machine, as shown in the drawing, the extruder ( Between the 1) and the feed conveyor 3 of the molding machine, the first and second storage loop conveyors 5a, 5b with rolls 4 are spaced apart, and the first and second storage loop conveyors 5a, 5b are It is connected to each other via the frame 6 to move up and down in accordance with the operation of the sensors 7 to adjust the increase and decrease of the extrudate (2).

And the device for raising and lowering the frame 6 of the first and second storage loop conveyors 5a and 5b uses a known lifting cylinder or similar lifting mechanism that operates by receiving electrical signals from the sensors 7. do.

In general, the extruded product 2 extruded through the extruder 1 generates heat due to its manufacturing characteristics, so that the extruded product 2 is loop-stored and supplied to the first and second storage loop conveyors 5a and 5b to undergo a cooling process after extrusion. The rolls 4 of the first and second storage loop conveyors 5a and 5b are operated by a motor to maintain the extrudate 2 in a loop for a predetermined time.

On the other hand, due to the rubber properties of the extrudate 2, the shape of the semi-finished product is changed when left for a long time, there is a possibility to make a defective product should be stored while minimizing the stop time of the extrudate (2).

In the present invention, the extrudate 2 extruded from the extruder 1 is transferred to the feed conveyor 3 of the molding machine while having a constant loop by the first and second storage loop conveyors 5a and 5b.

The first and second storage loop conveyors 5a and 5b are configured in the form of a conveyor which is started and stopped according to the loop amount of the front end portion by the rolls 4 driven by the respective motors, and the number of the storage loop conveyors is shown in the drawing. Although not shown in the figure, it can be installed in multiple numbers depending on the workload.

In addition, each storage loop conveyor may be installed on a separate frame to move up and down by using individual lifting cylinders as needed.

Next, the operation of the present invention will be described.

The extruder (2) from the extruder (1) is continuously supplied to the feed conveyor (3) of the molding machine at the normal position, which is the solid position of FIG. 2, and the extruder (1) operates when the machine stops due to failure of other equipment. The feed line of the extrudate 2 is continuously running without stopping and the extrudate 2 is stored in a loop in the first and second storage loop conveyors 5a and 5b, i.e. the first and second storage loops. When the conveyors 5a and 5b are full in the normal position, the sensors 7 detect this and move the frames 6 of the first and second storage loop conveyors 5a and 5b from the solid line position in FIG. 1 to the dotted line position. It is possible to further store the loop amount of the extrudate 2 as it rises by using a known cylinder lifting mechanism, and it is possible to store an increase in the amount of extrusion by repetition of this action.

In addition, when the first and second storage loop conveyors 5a and 5b are raised to increase the loop amount of the extrudate 2, the supply speed of the extrudate 2 discharged from the extruder 1 is reduced and supplied. It is supposed to be.

When the cause of failure is released, the stored extrudate 2 is used to perform the operation. In this case, the first and second storage loop conveyors 5a and 5b are lowered to consume the stored extrudate to return to the normal position. do.

In addition, the present invention is the extrudate 2 discharged from the extruder 1 while the first, second storage loop conveyor (5a, 5b) is up from the normal position, that is, returning to the normal position again from the time when the storage is carried out (2) By reducing the supply speed of the) is to ensure a longer storage time compared to the same storage amount, while the first and second storage loop conveyor (5a, 5b) is returned to the normal position, the extrudate (2) The feed rate is also adjusted to return to the original position.
