JPS6114909A - Winding device of stock rubber around roll - Google Patents

Abstract

PURPOSE:To surely wind kneaded stock rubber around the surface of a mixing roll by a structure wherein an adhesive mass coating device and a contact-bonding means are provided near the mixing roll. CONSTITUTION:When stock rubber W is extruded in sheet from between mixing rolls 1a and 1b and hung down, a coating device 2 is put into actuation in order to spray adhesive mass G against the mixing roll 1b. When the sheet-like stock rubber lies on a belt conveyer 5, a cylinder 7 is put into actuation so as to raise the belt conveyer 5 in order to bont the tip of the stock rubber by contacting with the surface of the mixing roll 1b. After a certain period of time has past since the winding of the sheet-like stock rubber W around the mixing roll 1b strats, the conveyer 5 is lowered to its original position.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device for winding a rubber material onto a roll.
More specifically, the present invention relates to a winding device that quickly and reliably winds kneaded rubber material around the surface of a kneading roll.

[Prior art]

Conventionally, when a rubber material kneaded in a kneading machine is further kneaded on a kneading roll, an operator supports the sheet-like rubber material coming out of the kneading roll with their hands or the like and wraps it around the kneading roll surface. They also assisted in removing rubber materials.

However, the above-mentioned work is extremely dangerous, requires skill, and requires speed, and there is a problem that the work efficiency is extremely low if the worker performs the work manually. .

Another problem was that it was very difficult to automate the kneading rolls.

[Purpose of the invention]

This invention was devised by focusing on the conventional problems, and its purpose is to automatically and reliably wrap the rubber material to be kneaded around the kneading roll surface. The purpose of the present invention is to provide a device for winding a rubber material onto a roll that can be easily operated for winding the rubber material around the kneading roll.

[Structure of the invention]

In order to achieve the above object, the present invention includes a coating device that sprays an adhesive near the kneading roll to make the rubber material adhere to the kneading roll surface, and a pressure bonding device that forcibly presses the tip of the rubber material to the kneading roll surface. The gist is that the means have been provided.

(Example of the invention) The present invention will be described in detail below based on the accompanying drawings.

FIG. 1 shows a schematic configuration diagram of a winding device embodying the present invention, and this winding device consists of a pair of left and right kneading rolls la, l.
b, an adhesive applicator 2 (spray nozzle) provided near the top of one of the kneading rolls lb, and a kneading roll l
It is composed of a pressure bonding means 3 provided at the lower part of the cylinder a and lb.

The adhesive G sprayed onto the surface of the kneading roll 1b from the coating device 2 is used to bring the tip of the kneaded rubber material W into close contact with the surface of the kneading roll 1b, and the adhesive G is sprayed onto the surface of the kneading roll 1b. Detection of etc. I! 4, and the spraying time is controlled to be constant.

In addition, the crimping means 3 includes a belt conveyor 5 disposed parallel to the lower part of the kneading rolls la and lb, a drive motor 6 provided at the lower part of the kneading roll 1a that drives the belt conveyor 5, and a belt conveyor 5. It is composed of an elevating cylinder 7 that is moved up and down below the kneading roll lb.

The belt conveyor 5 rises as shown by the two-dot chain line with the drive shaft 8 of the drive motor 6 as a fulcrum by the telescopic operation of the elevating cylinder 7, and the sheet of rubber material W hanging down from between the kneading rolls la and lb is lifted. The tip of the kneading roll 1b
It is pressed onto the surface of the

Note that the pressure bonding means 3 is not limited to the above embodiment, and any device may be used as long as it is a means for pressure bonding the sheet-like rubber material W to the surface of the kneading roll 1b.

Note that IO is a scraper for stripping off the rubber material W that is in close contact with the kneading roll 1a.

Next, the operation of the present invention will be explained based on FIGS. 2 to 5.

First, the rubber material W kneaded and discharged from a kneader (not shown) is kneaded again in kneading rolls la and lb.

While being kneaded again by the kneading rolls la and lb, when the rubber material W is extruded from between the kneading rolls la and lb in the form of a sheet and hangs down, the tip of the rubber material W is detected by the detector 4. is detected, and at the same time, the coating device 2 is activated.

The adhesive G is sprayed from the coating device 2 toward the surface of the kneading roll ib (see FIG. 2).

Next, when the sheet-like rubber material W is extruded and its tip is placed on the belt conveyor 5 as shown in FIG. The tip of the rubber material W on the conveyor 5 is pressed against the surface of the kneading roll lb as shown in FIG.

At this time, the coating device 2 is stopped.

The tip of the sheet-like rubber material W is wrapped around the kneading roll lb, and after a certain period of time has elapsed, the lifting cylinder 7 starts to contract and lowers the belt conveyor 5 to its original position, and the drive motor 6 also stops (fifth (see figure).

Such an operation is continued until the kneading of the rubber material W is completed, and when the kneading operation is completed, the rubber material W is taken out as a sheet and transferred to the next process.

Such operations are repeated.

〔Effect of the invention〕

As described above, the present invention includes an applicator that sprays an adhesive near the kneading roll for adhering the rubber material to the kneading roll surface, and a pressure bonding means that forcibly presses the tip of the rubber material to the kneading roll surface. Since the rubber material to be kneaded can be automatically and reliably wrapped around the kneading roll surface, the work of wrapping the rubber material around the kneading roll can be done safely and quickly. It is possible to improve work efficiency.
