Abstract

PURPOSE:To reduce the cost of equipment by cutting kneading material without making use of a cutting device, by a method wherein at a stage when kneading operation is completed, the tip side of a reversal conveyor is extended to the next process, the sheetlike kneading material is ruptured by performing reversal driving of a rollback conveyor, transmounted onto the reversal conveyor and taken out to the next process. CONSTITUTION:A sheetlike kneading material Wa discharged through rekneading rolls 11a, 11b is transmounted to a reversal conveyor 14 by conveying the same by a discharge conveyor 13. The kneading material Wa transmounted to the reverseal conveyor 14 is fed onto the rolls 11a, 11b again by a rollback conveyor 19 and the kneading material Wa is kneaded while making the kneaded material Wa sheetlike. At a stage when kneading operation of the kneading material Wa is completed, a tip side 14a of the reversal conveyor 14 is extended to the next process side and reversal driving of a driving motor of the rollback conveyor 19 is performed. The sheetlike kneaded material Wa is ruptured on the rekneading rolls 11a, 11b by its driving force, transmounted onto the reversal conveyor 14 and taken out to the next process.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a method for cutting and discharging mixed wire material in a repeating device, and more specifically, to a method for lowering the temperature of kneaded material discharged from a kneading roll. This is a repeating device that cuts the kneaded material and carries it out to the next process without using a special cutting device. The present invention relates to a method for cutting and discharging cross-conducting materials in a process.

[Prior art]

Conventionally, in order to keep the physical properties of a kneaded material such as a rubber material in a constant state, the kneaded material wrapped around the kneading roll surface is peeled off and then returned to the kneading roll in a balled state. A tandem type kneader is known, in which a plurality of kneading rolls are arranged in series and kneading materials are sequentially fed in, and the kneading work is repeated.

By the way, when kneading the kneaded materials repeatedly using the above method, there are issues with workability and installation space.

There were many problems in terms of equipment costs, etc.

The solution to these problems was a kneading material repeating device (
(Japanese Patent Application No. 311717/1983).

In the kneading material repeating device, Fig. 3(a) to Fig. 3(
As shown in d), the sheet-like kneaded material W repeatedly discharged from the rolls la and lb is received by the discharge conveyor 2, and the kneaded material W is conveyed by the discharge conveyor 2 and transferred to the reversing conveyor 3. , and further this reversing conveyor 3
The kneaded material W transferred from the roll is returned to the conveyor 4.
The kneaded material W is repeatedly kneaded while being repeatedly fed onto the rolls la and lb to form it into a sheet.

Then, when the kneading work of the kneading material W is completed,
As shown in FIG. 3(b), the tip side 3a of the reversing conveyor 3 is extended to the next process side, and as shown in FIG. 3(C), the cutting device 5 is used to knead the annular sheet. Material W
A portion of the material is cut and conveyed to the next process by a reversing conveyor 3 (FIG. 3(d)).

[Problems to be Solved by the Invention] However, when cutting a part of the sheet-like kneaded material W, the cutting device 5 is driven as described above and the cutting is performed with a rotary cutter, a push-cut cutter, etc. Therefore, the cutting device 5
It requires a large amount of money to install and control mechanisms, and there is also the problem that the unvulcanized kneaded material W adheres to or wraps around the cutter 5a, which often causes trouble. Therefore, work efficiency is extremely poor,
It was not possible to improve productivity.

[Object of the Invention] This invention was devised by paying attention to the problems of the prior art, and its purpose is to omit the conventional cutting device and to perform kneading using the reverse driving force of the roll return conveyor. By cutting the material and simplifying the entire device, equipment costs can be reduced, and the kneaded material will not stick to the cutter.
The object of the present invention is to provide a method for cutting and discharging cross-wire material in a repeating device, which completely eliminates troubles such as winding, and significantly improves work efficiency and productivity.

[Means for Solving the Problems] In order to achieve the above object, the present invention drives either a reversing conveyor or a roll return conveyor in reverse at the stage where the kneading work of the kneaded materials is completed, thereby: The gist of this method is to break the sheet-like kneaded material and transport it to the next process.

[Action of the invention]

The present invention is configured as described above, and when the kneading work of the kneaded materials is completed, either the reversing conveyor or the roll return conveyor is driven in the reverse direction, and the reverse driving force is used to form a sheet. It is designed to break the kneaded material.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows a schematic configuration diagram of a repeating device embodying the present invention, in which lla and llb indicate repeating rolls supported by a frame 12 and arranged horizontally, and the lower parts of the repeating rolls lla and llb are is the repeated roll lla,l
A discharge conveyor 13 for receiving the sheet-like kneaded material Wa discharged from the lb is horizontally installed so as to be inclined upward at a predetermined inclination angle toward the discharge side.

On the discharge end 13a side of the discharge conveyor 13, there is installed a reversing conveyor 14 on which the kneaded material Wa discharged from the discharge conveyor 13 is transferred. It is constructed so that it can pivot upward.

That is, the support frame 15 supporting the reversing conveyor 14
is divided by a shaft 16 serving as the fulcrum 0, and the frame 15a on the distal end side is configured to be able to pivot upward via a cylinder 17. Further, reference numeral 18 indicates a drive motor for the reversing conveyor 14.

Above the reversing conveyor 14, a roll return conveyor 19 is installed which supports the cylinder 17 and receives and receives the kneaded material Wa from the reversal conveyor 14. The drive motor 20 is configured to be driven by a drive motor 20 that can be used.

The tip side 19a of the roll return conveyor 19 is disposed on the repeating roll 1la11b, and the reversing conveyor 1
From step 4, the kneaded material Wa taken from the receiver is repeatedly rolled into roll 1la.
11b, and is configured to repeatedly knead the kneaded material W while forming it into a sheet.

Next, the kneading method and cutting/discharging method of the mixed wire material Wa are as follows.

Then, the kneaded material Wa transferred from this reversing conveyor 14 is repeatedly supplied onto the rolls 1la11b by the roll return conveyor 19, and is repeatedly kneaded while forming the kneaded material Wa into a sheet form.

In this way, when the kneading work of the kneaded material Wa is completed, the tip side 14a of the reversing conveyor 14 is extended to the next process side as shown in FIG.
As shown in FIG. 2(d), by driving the drive motor 20 of the roll return conveyor 19, which is capable of forward and reverse rotation, in the reverse direction, the sheet-like kneaded material Wa is repeatedly moved onto the rolls 1la11b by its driving force. The sheet is broken at the point where it is broken, and then transferred onto the reversing conveyor 14 and carried out to the next process.

By repeating these operations, the sheet-like kneaded material Wa can be efficiently kneaded, cut in a suitable state, and transported to the next process without using a conventional cutting device. It is.
