Description

Description: TECHNICAL FIELD The present invention relates to a five-roll calendar and a calendar device.

[Prior Art] Roller calendars for rolling rubber, plastics, and the like are mainly four-roll calendars. However, in order to meet demands for quality improvement, there is a transition to a five-roll calendar with a large number of banks.

2. Description of the Related Art A conventional five-roll calender and a calendar device are described in JP-B-49-44586 and JP-A-62-7519, and have an inverted-L type as shown in FIG. There are various types such as L type and M type as shown in FIG.

First, the inverted L-type five-roll calendar shown in FIG.
Roll No. 1 and Roll No. 2 are arranged horizontally upward, and
The third roll 3, the fourth roll 4, and the fifth roll 5 are sequentially arranged in a vertical straight line below the second roll 2,
The material 7 kneaded by the continuous kneader 6 is supplied by the conveyor 8 to the first bank 9 between the first roll 1 and the second roll 2, and the co-supplied material 7 is supplied to the first bank 9 and the second roll 9. Rolls are sequentially rolled in a second bank 10 between rolls 2 and 3, a third bank 11 between rolls 3 and 4 and a fourth bank 12 between rolls 4 and 5. Then, it is taken out by a take-off roll (not shown).

The L-type five-roll calendar shown in FIG. 3 has a first roll 1 and a second roll 2 disposed horizontally below, and a third roll 3 and a fourth roll 4 above the second roll 2. No. 5 rolls 5 are sequentially arranged in a straight line in the vertical direction.
The same operation as that of the inverted L-type five-roll calendar shown in the figure is performed.

Similarly, the M-type five-roll calendar shown in FIG. 4 has a first roll 1 and a second roll 2 disposed horizontally above, and a third roll 3 disposed below a second roll 2. The fourth roll 4 is horizontally arranged on the opposite side of the first roll 1 of the third roll 3,
The fifth roll 5 is disposed below the fourth roll 4, and performs the same operation as that of the inverted L-type five-roll calender shown in FIG.

[Problems to be Solved by the Invention] However, the above-described conventional five-roll calendar and calendar apparatus have the following problems.

The inverted L type shown in FIG. 2, the L type shown in FIG. 3, and the M type shown in FIG. 4 generally have a large height and a large size. , 11,12 could not be operated while directly monitoring. For this reason, auxiliary means such as an industrial TV are required, and it is difficult to monitor while performing other work, such as watching on a monitor installed at a fixed position, so that multiple operators are always required for operation. I was

In the case of the inverted L type shown in FIG. 2 and the L type shown in FIG. 3, since the four rolls 2, 3, 4, 5 are aligned in the vertical direction, the rolls 1, 2, 3, 4, 5, In order to be able to adjust the gap between the rolls, the rolls 1, 2, 3, 5 can be moved in the direction shown by the arrow in the figure, and the roll 4 is fixed or the direction shown by the arrow by a roll crossing device (not shown). Rolls 2 and 3 adjacent to each other
Since the moving directions are the same, a structure for movably attaching the frame supporting the second roll 2 to the frame supporting the third roll 3 is required, and the structure is complicated.

In the case of the inverted L type shown in FIG. 2 and the M type shown in FIG. 4, since the position of the first bank 9 to which the material 1 is supplied becomes higher, the conveyor 8 is used to supply the material 7 kneaded in the continuous kneading 6. Is required, and the material 7 cools while being conveyed by the on-bearing 8.

In order to improve the operability described in the preceding paragraph, the M type in FIG. 4 has a continuous kneader 6 installed on the same floor as a five-roll calender, and a roll arrangement of approximately 45 ° as shown in FIG. But in this way, rolls 1,2,3,
4 and 5 act as lids, and the volatiles released from material 7 are trapped in the lower part of rolls 1, 2, 3, 4, 5
The monitoring of 10, 12 was hindered.

SUMMARY OF THE INVENTION An object of the present invention is to provide a five-roll calendar and a calendar device in which the above problems are solved by devising the arrangement of rolls.

[Means for Solving the Problems] The present invention relates to a five-roll calender for molding rubber and plastic in a belt shape, wherein a rubber and plastic supply position is a first roll and a second roll is disposed obliquely above the first roll. And the third, fourth, and fifth rolls are respectively positioned in the lower area of a straight line connecting the centers of the first and second rolls, and The present invention relates to a five-roll calender characterized in that the rolls are arranged so as to extend diagonally upward from the third roll along a straight line connecting the centers of the first and second rolls. 1
The present invention relates to a calendar device having the five-roll calender provided at substantially the same height as the No. roll and the take-off roll provided on the side opposite to the No. 4 roll.

[Operation] Since the arrangement of the rolls is N-shaped, the height dimension is reduced and the size is reduced, so that even one worker can operate while monitoring all the banks.

Since the adjustment of the gap between the rolls is performed by moving all the rolls in a direction orthogonal to the moving direction of the adjacent roll, the mechanism for adjusting the gap between the rolls is simplified and the structure of the frame is simplified.

Since the arrangement of the rolls is N-type, it is possible to prevent volatiles radiated from the material from being trapped in the lower part of the rolls and obstructing the monitoring of the bank.

Since the height of the first bank to which the material is supplied is reduced, 1
The material can be directly supplied from a material supply device provided at substantially the same height as the number roll.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

 FIG. 1 shows an embodiment of the present invention.

The second roll 14 is disposed obliquely above the downstream side in the supply direction a of the material 25 of the first roll 13, and the third roll 15 is
The fourth roll 16 is disposed diagonally below and opposite to the first roll 13, the fourth roll 16 is disposed diagonally above and opposite to the second roll 14 of the third roll 15, and the fifth roll 17 is disposed in the fourth roll 16. Of the rolls 13 and 1
First bank 18, second bank 19, third between 4,15,16,17
An N-type five-roll calendar 22 having a bank 20 and a fourth bank 21 is formed.

A take-off roll 26 is provided downstream of the material 25 of the fifth roll 17 in the feed direction a.

The continuous kneader 24 is attached to the first bank 18 with the dice 23 facing.

A molten material 25 such as rubber or plastic kneaded by a continuous kneader 24 is directly supplied from a die 23 to a first bank 18 between a first roll 13 and a second roll 14, and the supplied material is supplied.
25 to the first bank 18, the second bank 19 between the second roll 14 and the third roll 15, the third bank 20 between the third roll 15 and the fourth roll 16, between the fourth roll 16 and the fifth roll 17 Of the fourth bank 21
Are rolled in a belt shape in order, and are taken out by the take-off roll 26.

At this time, since the arrangement of the rolls 13, 14, 15, 16, 17 is N-type, the height of the five-roll calendar 22 is reduced and the size is reduced. 19,2
It is possible to operate while monitoring 0,21.

Adjustment of the gap between the rolls 13, 14, 15, 16, 17 is performed by moving the rolls 13, 14, 15, 17 in the moving direction of the adjacent rolls 14, 15, 16, 17 as indicated by arrows in FIG. Since the movement is performed in a direction orthogonal to the direction, the structure of the gap adjusting mechanism of the roll and the structure of the frame are simplified.

Note that the roll 16 can be fixed or a roll crossing device (not shown) can correct a change in the width direction of the gap between the rolls 15 and 17 and the roll 16 caused by bending of the rolls 15 and 17 during rolling. To do.

Since the arrangement of the rolls 13, 14, 15, 16 and 17 is N-type, the volatile matter radiated from the material 25 causes the rolls 13, 14, 15, 16, 17
From the lower part of the bank, volatile matter is in the banks 18,19,20,21
Is prevented from obstructing the monitoring of the information.

Since the height of the first bank 18 to which the material 25 is supplied is reduced, the material 25 can be supplied directly from the continuous kneader 24, and a conveyor can be dispensed with.

Note that the five-roll calendar and the calendar device of the present invention are not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.

[Effects of the Invention] As described above, according to the five-roll calender and the calendar device of the present invention, the following various excellent effects can be obtained.

Since the arrangement of the rolls is N-shaped, the height is reduced and the size is reduced, so that even one worker can operate while monitoring all the banks.

Since the adjustment of the gap between the rolls is performed by moving all the rolls in a direction orthogonal to the moving direction of the adjacent roll, the mechanism for adjusting the gap between the rolls and the structure of the frame are simplified.

Since the arrangement of the rolls is N-type, particularly, heat and volatiles radiated from the material supplied to the supply position between the first roll and the second roll are trapped in the lower part of the third roll, and the bank Is prevented from obstructing the monitoring of the information.

Since the height of the first bank to which the material is supplied is reduced, the material can be supplied directly from the material supply device placed on the same floor as the calendar.
