Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for rolling up a rubberized material, and more specifically, the present invention relates to a device for winding up a rubberized material, and more specifically, a device for winding up a rubberized material, such as a band-shaped sheet obtained by cutting a tire cord-containing rubber sheet on a bias, while a liner is interposed on the contact surface. This invention relates to an improvement in a device for continuously winding cells.

Conventionally, this type of apparatus, as shown in FIG. 1, includes a winding shaft 2 to which a cell 1a for winding up a rubberized material a is attached, and a liner b supplied between the material a during winding. Since the liner unwinding shaft 3 to which the cell 1b wrapped with the liner is attached is arranged separately, when the rubberized material is rolled up, when the material a is rolled up with the liner b on the cell 1a, , then stop the rolling device, remove this cell 1a from the winding shaft 2, and roll out the liner b to remove the empty cell 1b.
is removed from the liner winding shaft 3 and attached to the winding shaft 2, and a new liner b is attached to the liner winding shaft 3.
After the wrapped cell 1b is attached, the device is operated again and the winding shaft 2 is driven to continue the winding operation.

As mentioned above, in the conventional device, it is necessary to change the liner from the liner unwinding shaft 3 to the unwinding shaft 2 each time the winding of one cell is completed, which reduces the winding work efficiency within a unit time. There are problems in that not only is this significantly hindered, but also handling and other efforts are required. There is also a method of installing a plurality of the above-mentioned devices in order to improve work efficiency, but this requires a plurality of drive devices to drive the winding shaft 2. In this case, a switching device such as an electromagnetic clutch is required, and in any case, the entire device becomes large and there is an economical problem.

The present invention has been made in view of the above-mentioned current situation, and it is also an object of the present invention to provide an extremely effective and suitable device for rolling up rubberized material, which solves the problems of the conventional devices.

The feature is that a shaft is rotatably attached to the end of each arm of a rotating body that is rotatably installed on the machine frame and has multiple arms arranged radially around the periphery. A driven portion is formed on one side of the shaft, and a cell attachment portion is formed on the other side, and when rolling up the rubberized material, the driven portion of the shaft is driven by a separately provided drive device. At the point.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The winding device of the present invention will be described below by way of embodiments with reference to the drawings.

The device E for rolling up rubberized material shown in FIG. 2 and FIG.
In this device, five arms 5a are provided radially around a rotating body 5 rotatably attached to a machine frame 4, and each arm 5a is A shaft 6 is rotatably attached to the tip of the arm 5a in a direction perpendicular to the arm 5a.

Each of the shafts 6 is provided with a driven portion 6a on one side and a cell attachment portion 6b on the other side to form a winding device main body A.

A driving device B is provided adjacent to the side of the winding device main body A, which connects with the driven portion 6a of the shaft 6 and rotates the shaft 6 when winding up the rubberized material.

In addition, in the above embodiment, the arm 5 is attached to the rotating body 5.
Although five shafts 6 are provided through a, the number is not particularly limited, and is preferably about 5 to 10 shafts.

That is, when the number of arms 5a and shafts 6 is reduced to five or less, cells must be replaced frequently in a short period of time as in the conventional method, and therefore the winding workability within a unit time is reduced. Not only is this a hindrance, but it also causes handling and other problems that require a lot of effort and time. Incidentally, the time it takes to wind up one cell is about 2 minutes, and when two to three arms 5a and shaft 6 are used, it is always necessary to replace the cell every 5 minutes. Stopping the line every time would result in very poor work efficiency and require a worker to be on hand at all times.
There is also the problem of poor work efficiency.

In addition, when the number of arms 5a and shafts 6 is 10 or more, unless the span of the cantilevered arm 5a is lengthened, when the rubberized material is rolled up, it may interfere with the neighboring rubberized material being rolled up. In addition, there is the problem that the entire device becomes large and it takes a lot of effort and time to replace the cells.

Therefore, when the rotating body 5 is provided with the shaft 6 via the arm 5a, it is preferable that there be at least 5 shafts and 10 shafts or less.

The drive device B, as shown in FIG.
A chain 10 is installed between sprockets 8 and 9 that are rotatably provided at the upper and lower parts of the column 7, respectively,
By rotating the lower sprocket 9 by an electric motor 11, the chain 10 is configured to run in one direction (in this embodiment, the direction of the arrow).

Further, each driven portion 6a of the winding device main body A
In this embodiment, a sprocket 12 is attached to the end of each shaft 6, and when the rubberized material a is rolled up, the shaft 6 with the winding cell 1a attached to the cell attachment part 6b is The driven part 6a, that is, the sprocket 12 is connected to the chain 1 on which the drive device B runs.
0, the winding cell 1a can be rotated via the sprocket 12 and the shaft 6.

Reference numeral 13 designates a motor for driving a rotating body, and a sprocket 14 attached to the shaft end of the motor and a sprocket 15 attached to the shaft end of the rotating body 5 are connected by a chain 16. 13, the rotating body 5
can be rotated one index at a time.

Next, the state of rolling up the rubberized material a by the present rolling up device E will be explained.

First, as shown in FIG. 2, the winding cell 1a is attached to the cell attachment part 6b of the shaft 6 whose driven part 6a (sprocket 12) is in contact with the chain 10 of the drive device B, and the winding cell 1a is attached to the cell attachment part 6b of the shaft 6, and the other shaft 6 is attached. The liner rolling-out cells 1b each wrapped with a liner b are attached to the cell attachment portions 6b, and then the end of the rubberized material a is attached to the core of the rolling-up cell 1a, and the rolling-up cell 1a The end of the liner b is pulled out from the liner rolling-out cell 1b located above the rubberized material a and attached to the rolling-up cell 1a.
Attach it to the top of the . With the above, the first winding preparation is completed, and here the electric motor 1 of the drive device B
When the chain 10 is energized, the chain 10 runs in the direction of the arrow, and the winding cell 1a rotates via the driven part 6a (sprocket 12) of the shaft 6 that meshes with the chain 10, and the winding cell 1a rotates to spread the rubberized material a onto its contact surface. The film can be rolled up into the winding cell 1a with the liner b interposed therebetween.

When the first winding is completed, the rubberized material a is cut and the rotating body driving electric motor 13 of the winding device main body A is energized to rotate the rotating body 5 one index counterclockwise. Then, in the first winding operation, the liner unwinding cell 1b, which has been emptied by rolling out the liner b, moves to the first winding position, and the liner unwinding cell 1b, which is emptied by rolling out the liner b, moves to the first winding position, and is then rubberized as in the first winding operation. Attach material a and liner b and
Perform the second turn.

When the second winding is completed, the liner b is rolled out in the second winding operation as described above, and the empty liner winding cell 1b is moved to the winding position. Perform the third winding in the same manner.

In this example, as shown in the figure, liner b
Since four rolled cells 1b are attached, the winding work for four cells can be carried out without replacing the cells.

Since the present invention is constructed as described above, unlike the above-mentioned conventional devices of this type, each time the winding into one cell is completed, the empty liner winding cell is replaced or the liner is rolled up. There is no need to attach additional cells, and therefore not only can the winding work efficiency within a unit time be significantly improved, but also the labor involved in handling etc. can be reduced.

Further, the device of the present invention includes a winding device main body A in which a plurality of arms are arranged radially around one rotary body, each arm is provided with a shaft for attaching each cell, and a drive for rotating the shaft. Since it is compactly constructed from the device B, the installation area can be significantly reduced, which is economical. Furthermore, since this invention has at least five arms and shafts, it is possible to solve the problem of having to frequently replace cells in a short period of time, which was the case in the past. In addition to improving the winding work efficiency, there are no handling or other issues that require much time and effort, and the line does not have to be stopped frequently to replace cells, and workers are always on hand. This has the effect of significantly improving work efficiency.
