Abstract

PURPOSE:To avoid the occurrence of stain in turning the inside of a rubber element out by using a surrounding roller unit consisting of grooved reversible rollers and many collar rolles. CONSTITUTION:An unvulcanized rubber element 20 sent by a carry-in roller conveyer 18 is directed between a grooved reversible roll 1 turning in the direction of inducing the rubber element 20 and many surrounding collar rollers 6 combined with each other, directionally changed through 180 deg. along the periphery of the grooved reversible roll 1, and sent out. On the outlet, the rubber element ready to go along the circumference of the roll 1 by rejected by the rejecting collar roller 12, separated from the roll 1, guided to a carry-out roller conveyer 19, and over turned there.

Description

[Detailed description of the invention] This invention 1. Unvulcanized rubber that is easily plastically deformed: H

The present invention relates to a rubber material turning device in which IC11 is added to 1'i.

i, Y, 31ζ, For example, processing of a rubber material such as a band-shaped tie i-red material in which a rubber compounded fabric is extruded from an extruder.In one weighing machine, the necessary turning operation can be carried out by two people. , a method of turning over a long belt-shaped tire tread material one by one by holding both ends, and placing it on the outside of the inner sandwich belt 23 that is hung on a 5-turn roll 22 as shown in FIG. 6. Two methods are known: one is to hang the outer belt 24 for a sandwich, and place a band-shaped tire tread material in a sandwich state between the two belts, the inner belt 23 and the outer belt 24, and turn it over. It was getting worse.

In the former method, since the material handled is unvulcanized raw rubber compounded fabric, it is a material that does not easily undergo plastic deformation, so unnecessary tensile stress acts, causing distortion that is harmful to quality. This also adds fluctuations due to variations among workers.

In the latter method, glue applied to the material for another purpose may adhere to the bells 1~ and solidify, impairing product quality, which may cause harmful effects, and the meandering of the belt may cause the straight hemp after being turned over. However, it had disadvantages such as damage to the

Therefore, with the aim of eliminating these conventional drawbacks, we investigated the reasons for this, and as a result, we developed a grooved 4-hole O-roll instead of a plain rotating roll.
By using a belt, eliminating the full-surface pressure bonding type gluedip mechanism using a belt, and using a surrounding roller unit consisting of a large number of collar rollers, it is possible to obtain a good mangae material 1. be.

Next, aspects of this unique rubber material turning device will be described in detail with reference to illustrative drawings.

A surrounding roller unit consisting of a large number of brim rollers is set on the outer half of the reversing roll with a predetermined distance between them, and a groove is formed between the diameter of the reversing roll and the diameter of the boxwood roller. The rubber material is conveyed to form a predetermined gap δ. In order to transfer the material to the transport roller conveyor A7-, one side is provided.

Therefore, the grooved reversing roll, the collar roller, and the splashing mechanism are set on one common frame.

FIG. 3 is a partially cutaway view of a surrounding roller unit of a large number of collar rollers arranged in combination.

Since FIG. 4 shows an embodiment opposite to the loading path of FIG. 1, FIG. 5 shows another embodiment of the spring mechanism.

Next, the fully loaded reversing roll, the collar and the splash mechanism will be described in detail.

As shown in FIGS. 1 and 2, the reversing roll has a large number of grooves 1a formed on its outer circumferential surface.

It is rotated in the transport direction by a chain gear mechanism consisting of a drive chain 5 and a drive chain 5.

The brim roller group uses a disc-shaped brim 6a, which has an appropriate thickness depending on the type of rubber material to be conveyed, on a roller shaft 7.

In order to smoothly increase the driving performance, m multiple transmission chains 11 are connected.

The direction of rotation is not shown by the arrow iJ3, and it is rotated in the direction 1i opposite to the direction of rotation on the grooved reversing roll.

As shown in FIG.

In addition, a splashing mechanism is set at the outlet of the reversing conveyance section formed between the reversing roll 1 with m and the surrounding roller unit I-S R consisting of a large number of brim rollers. As this splash mechanism, a splash roller 12 is exemplified.

Although the structure is such that the rubber cable 4A20 is conveyed from the top to the bottom, the function of (() is exactly the same as in the case of FIG. 1 described above.

The embodiment shown in FIG. 5 is equipped with a wedge-shaped splash block 21 in place of the splash roller 12 of the splash mechanism in the embodiment shown in FIG. It is something.

Its action is the same as described above: it repels the rubber material 20 that is being fed along the grooved reversing roll 1, separates it from the grooved reversing roll 1, and guides it to the conveyance roller 719. It is something.

This splash block 21 is a grooved reversing roll 17)
The side along the 18th line has a one-node tooth shape and fits into the groove.
(This is the set point 1, so the tip of the rubber material is blocked by this splash block 21)
Reversal [1- The direction is changed from the line and the line is transferred horizontally. 1 As explained above, since the device of the present invention has the above-described configuration, when turning the rubber material inside out, no unnecessary stress is applied to the conventional manual process, which causes distortion. Moreover, since it is automatically operated, it has the effect of improving product quality and saving labor.
? It is something that can be done.

A special smooth conveyance structure such as a surrounding roller unit 1 consisting of a reversing roll is supported at a fixed position by a bearing (,f+J plastic rubber material). Applying meandering or distortion to <C<1', 1 can be turned over in a straight state.

In addition, since the grooved reversing roll and the surrounding roller of the brim roller have a comb-teeth-like rotating and feeding mechanism, the glue applied to the material is less likely to adhere to the material. Since the contact surface can be kept easily or automatically cleaned at all times, the quality of the product is not affected by foreign matter that has arrived, and a stable and good product can be obtained. .
