Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an outer peripheral surface of a roll shaft,
The present invention relates to a brush roll in which a large number of channel brushes are removably mounted in parallel in an axial direction and in which a channel brush mounting structure is improved.

[0002]

2. Description of the Related Art There are several types of brush rolls used for polishing and finishing steel plates, aluminum plates, etc., in which a method of implanting bristle material on the outer peripheral surface of the roll shaft is different. Among them, a type in which a long channel brush is spirally wound closely around the outer peripheral surface of a roll shaft is widely used. The channel brush has a structure in which a metal long channel having a substantially U-shaped cross section is used as a base member, and a bristle material that is pressed into a U-shaped shape by pressing a core wire is fitted over the entire length in the channel. ing.

For this reason, it is inevitable that a gap having a width twice as large as the thickness of the long channel is formed between the adjacent channel brushes wound spirally. or,
Since the inclination angle of the spiral is small, the planting density of the bristle becomes uneven in the roll axis direction, and this has been a factor of causing uneven polishing. Therefore, as one of the measures for eliminating the uneven polishing, a method of welding a number of straight channel brushes one by one to the roll surface in parallel with the axial direction of the roll axis has been considered.

However, channel brushes are used so severely that each one must be replaced with a new one almost every week depending on the usage. In addition, a material using synthetic resin bristle material having poor heat resistance has a problem that it is difficult to perform sufficiently strong welding. Therefore, in order to facilitate replacement of a damaged channel brush, a large number of insertion channels, in which the channel portions of each channel brush are slidably inserted respectively, are brought into close contact with the roll shaft surface in advance. There was also a method of welding.

According to the method in which the insertion channel is welded to the roll shaft, the replacement operation of the damaged channel brush can be performed easily and quickly, but the insertion channel is not provided between the adjacent channel brushes. A gap equal to twice the thickness of the side wall is formed. For this reason, the planting density of the bristle material must be coarse, and a new problem that the polishing performance and durability are reduced is derived.

Therefore, the applicant of the present application has newly devised a brush roll which can easily and quickly replace a damaged channel brush and has excellent durability and polishing performance.
A patent application has been filed as "Japanese Patent Application No. Hei 7-21548".

[0007] A schematic configuration of the brush roll of the prior application is that a plurality of channel brushes are removably mounted on the entire outer peripheral surface of the roll shaft in parallel with the roll axis direction.
As a mounting means, a plurality of hook members are fixed on the back side of the channel brush 1 at a predetermined interval, and at positions corresponding to the respective fixing positions, a blind rivet or the like protruding from the outer peripheral surface of the roll shaft is provided. A configuration is adopted in which each hook member is slidably engaged and disengaged with each hook member.

[0008]

However, an extremely large frictional force is generated between the outer peripheral surface of the roll brush and the object to be polished at the time of the polishing operation, so that the vibration of the brush roll is remarkably increased. Depending on the detachable mounting structure, it was difficult to obtain a sufficiently reliable locking strength.

Therefore, an object of the present invention is to make the most of the excellent features of the above-mentioned prior invention that the attaching and detaching operation of the channel brush can be performed extremely easily and quickly, and also have a sufficient mounting strength of the channel brush to the roll shaft. Another object of the present invention is to provide a brush roll assembling structure that can be ensured in the above.

[0010]

In order to achieve the above object, a brush roll assembling structure according to the present invention comprises a plurality of channel brushes arranged on an outer peripheral surface of a cylindrical roll in parallel with an axial direction thereof. In the detachably mounted one, small plate-like mounting members 3 are protruded from one side end of the back surface 1a at a plurality of positions on the back surface 1a of the channel 1 constituting the channel brush 10. A countersunk bolt 30 which is fixed in a state where it is made to fit and which is inserted into a bolt hole 4 provided in the protruding portion 3a is screwed to the peripheral wall of the cylindrical roll 101.

The channel brush 10 is preferably used as a dual brush unit 20 by integrally connecting the channels 1 and 1 of the two channel brushes arranged in parallel via the mounting member 3. The dual brush unit 20 includes two types of two types in which the mounting positions of the mounting members 3 are shifted from each other by at least the length of the mounting members 3.
0A and 20B are prepared and placed, and these two types may be alternately and closely screwed in the circumferential direction of the outer peripheral surface of the cylindrical roll 101. Alternatively, only one type of double brush unit 2
0 may be attached while being shifted from each other in the longitudinal direction by at least the length of the attachment member 3 so as not to hinder the close attachment of the adjacent two brush units 20. Further, a large number of channel brushes 10 or double brush units 20 are placed in a cylindrical roll 101 in close contact with each other.
At the time of attachment to the outer peripheral surface of the channel, the last attachment is to fix the heads of the bolts such as the countersunk bolts 30 at a plurality of locations on the back surface 1a of the channel 1 via the attachment members 6 or directly. It is preferable that each of these bolts is inserted through a bolt hole provided in the peripheral wall of the cylindrical roll 101 and then tightened with a nut. Further, it is preferable to fix the screw end fixing members 5 to both ends of the back surface of the channel 1. On the other hand, the outer peripheral surface of the cylindrical roll 101 may be provided with embedding grooves 101a, 101b into which the mounting members 3, 6, 5 are dropped. A large number of channel brushes 10 or double brush units 20 may be attached at a predetermined angle with respect to the axial direction of the cylindrical roll 101.

The double brush unit 20 is attached to the cylindrical roll 101 as described below.
6) Three types of double brush units 20A, 20B, and 20C having different mounting states or shapes are prepared. Of these, the same number of double brush units 20A and 20B are prepared, but only one double brush unit 20C is sufficient.

As shown in FIG. 3 to FIG. 5 and FIG. 8, on the back surface of the double brush unit 20A, as shown in FIG. The two channel brushes 10, 10 are integrated by welding the small rectangular plate-shaped mounting member 3 over the back surfaces 1a, 1a.

The mounting member 3 is a double brush unit 2
0A is also detachably screwed and fixed to the outer peripheral surface of the cylindrical roll 101, and the width dimension W is set to the width V of the rear surface 1a of the channel 1 as shown in FIG.
Is set to more than twice. Then, a part of the mounting member 3 is made to protrude from the side end of the one bottom surface 1a.

The projecting portion 3a is provided with a bolt hole 4 having a counterbore for inserting a flat head bolt 30 having a hexagonal hole. On the other hand, a screw hole a into which the flat head bolt 30 is screwed is provided at a position corresponding to the bolt hole 4 on the outer peripheral surface of the cylindrical roll 101.

As shown in FIGS. 3 to 5 and FIG. 10, one end of a strip-shaped end mounting member 5 is provided at each end of the back surface of the double brush unit 20A. Are welded so as not to protrude from both side edges in the width direction of the double brush unit 20A.

At the other end of the end mounting member 5, two long bolt holes 5a for passing bolts 31 for screwing to the outer peripheral surface of the cylindrical roll 101 are provided. On the other hand, the cylindrical roll 101
A screw hole b into which the bolt 31 is screwed is provided at a position corresponding to the long bolt hole 5a.

Next, the double brush unit 20B is shown in FIG.
6 and FIG. 6, the mounting position of the mounting member 3 on the bottom surface 1a of the channel 1 is at least as long as the length L of the mounting member 3 as compared with the double brush unit 20A. 8) is shifted in the longitudinal direction of the bottom surface 1a. This is because, when a large number of double brush units 20 are sequentially and closely screwed and fixed on the outer peripheral surface of the cylindrical roll 101 in a parallel manner, each of the two adjacent brush units 20 This is to prevent the protruding portion 3a of the mounting member 3 from interfering with the channel 1 of the other double brush unit 20 and hindering the close mounting.

On the other hand, as shown in FIGS. 2 and 8 to 10, the outer peripheral surface of the cylindrical roll 101 is provided at both ends of the back surface of each double brush unit 20 and at a plurality of places between the both ends. Embedding grooves 101b and 101a for dropping the fixed end mounting member 5 and mounting members 3 and 6, respectively.
Are provided at a plurality of locations corresponding to the respective mounting positions of the mounting members 5, 3, and 6.

Thus, the back surfaces 1a of all the channels 1 can be firmly brought into contact with the outer peripheral surface of the cylindrical roll 101 except for the mounting portions of the mounting members 5, 3, and 6 (see FIG. 2). . The groove width dimension of the embedding groove 101a is 2
The length is set to twice or more the length of the mounting member 3 so that the respective mounting members 3 of the two types of double brush units 20A and 20B can be shared.

Although illustration is omitted, a buffer material such as a urethane rubber plate may be buried in a portion of the burying groove 101a where the mounting members 3 and 6 are not fitted. Thereby, the double brush unit 20 is fixed to the outer peripheral surface of the cylindrical roll 101 more stably, but in a buffered state. Embedded groove 10
When 1a is not provided, a urethane rubber strip having substantially the same thickness as the mounting members 3 and 6 may be wound around the outer peripheral surface of the cylindrical roll 101 where the mounting members 3 and 6 do not abut. Good.

Next, FIGS. 7 and 9 show a case where a number of double brush units 20 are screwed and fixed to the outer peripheral surface of the cylindrical roll 101 sequentially from the first brush unit 20. Of 1
And the first double brush unit 2
The figure shows only one double brush unit 20C that is adjacent to 0.

The mounting member 6 for the double brush unit 20C is different from the mounting member 3 in that the width of the mounting member 6 is different from the channel 1 of the first double brush unit 20 described above.
In order to avoid interference with the brush unit, the brush unit 20 is set to have a small size that does not protrude from both side edges of the back surface of the double brush unit 20.

The mounting member 6 has a bolt hole 4 at the center thereof.
Is provided. The countersunk bolt 30 dropped into the bolt hole 4 has its head welded to the mounting member 6 to prevent idle rotation. On the other hand, on the outer peripheral surface of the cylindrical roll 101, bolt holes c through which the flat head bolts 30 are inserted are provided at respective locations corresponding to the bolt holes 4 of each mounting member 6. A nut 32 is screwed into the insertion end.

Next, how to assemble the brush roll 100 will be described. First, as shown in FIG.
A screw hole a into which the flat head bolt 30 is screwed, a screw hole b into which the bolt 31 is screwed, and a bolt hole c through which the flat head bolt 30 is inserted are provided at a number of predetermined places on the outer peripheral surface of 1.

Thereafter, the outer peripheral surface of the cylindrical roll 101 is
The first double brush unit 20A (or 20B) is mounted. First, as shown in FIG. 10, the end mounting members 5 at both ends of the double brush unit 20A are fixed at predetermined positions on the outer peripheral surface of the cylindrical roll 101. For that purpose, the bolt 31 inserted into the long bolt hole 5a may be screwed into the corresponding screw hole b on the outer peripheral surface.

Next, the bolt holes 4 of the protruding portions 3a of the mounting members 3 fixed at a plurality of positions between both ends are shown in FIG.
As shown in (1), when the flat head bolt 30 is inserted and screwed into the corresponding screw holes a on the outer peripheral surface, the first double brush unit 20A is firmly fixed at a predetermined position. In this state, the mounting members 3 and 5
Are dropped into the embedding grooves 101a and 101b provided on the outer peripheral surface of the rim. The head of the countersunk bolt 30 is buried in the counterbore of the bolt hole 4. Therefore, the back surface of the double brush unit 20A is entirely covered with the cylindrical roll 101.
Is firmly in contact with the outer peripheral surface of

Next, the attached double brush unit 20
A, the second double brush unit 20B is screwed and fixed in the same manner as described above by closely contacting the side where the part of the mounting member 3 protrudes. As described above, the two adjacent brush units 20A and 20B have the attachment position of the attachment member 3 shifted by at least the length thereof, as described above, so that the protruding portion 3a prevents close attachment. (See FIG. 11).

Thereafter, the same number of the remaining two brush units 20A and 20B are attached to the outer peripheral surface of the cylindrical roll 101.
What is necessary is just to mount it in a close state sequentially and alternately.

When the last one of the two brush units 20B and 20A has been attached, there is room on the outer peripheral surface of the cylindrical roll 101 for a single brush unit 20C to be left. It will be left. Attachment member 6 fixed to this double brush unit 20C
Differs from the mounting member 3 in that the dual brush unit 20
Since there is no portion protruding from the back surface of C, it can be fitted into the remaining space without any trouble.

In order to fix each mounting member 6 to the outer peripheral surface of the cylindrical roll 101, as shown in FIG.
A countersunk head bolt 30 having a head previously fixed thereto is inserted through a corresponding bolt hole c on the outer peripheral surface.
What is necessary is just to tighten with the nut 32 from the inside of 01. For places in the inner space of the cylindrical roll 101 that are not accessible, a special nut fastener commercially available that is considered for such places may be used. Since the above screwing and nut tightening are extremely simple operations, even a beginner of the operation can finish quickly and reliably.

With the brush roll 100 assembled in this manner, each of the two brush units 20 is connected to the cylindrical roll 10.
1 is fixed to the top surface of each countersunk bolt 30 shown in FIG.
As will be understood from FIG.
Channel 1 is firmly pressed against the bottom surface 1a. Therefore, there is no danger that each countersunk bolt 30 will be shaken violently with the polishing operation of the brush roll 100 rotating at high speed. Therefore, the screw holes a,
It is possible to almost certainly eliminate the risk that the edge of the hole b is gradually broken with time.

Each double brush unit 20 has a predetermined inclination angle with respect to the roll axis direction of the cylindrical roll 101.
In this embodiment, it is attached at an angle of about 7 degrees. Therefore, it is possible to avoid a problem in which a large polishing pressure is applied to the entire brush unit 20 at one time.

Therefore, the above-mentioned bolt blur prevention effect,
Further, by combining the two channel brushes 10 and 10 into one, the durability of each channel brush 10 is remarkably increased in combination with the effect of improving the rigidity of the dual brush unit 20, and a good polishing performance is obtained. Can be maintained for a longer period of time. The replacement work of the damaged double brush unit 20 can be performed simply and quickly by only attaching and detaching bolts.

By the way, in the above embodiment, two types of double brush units 20 having different mounting positions of the mounting member 3 are used.
A and 20B are prepared. However, if the mounting position of a large number of double brush units 20 on the cylindrical roll 101 is shifted in the roll axis direction by the width of the mounting member 3 for every other brush unit 20, only one type of double brush unit 20 can be obtained. Brush unit 20A (20
B) and a single double brush unit 20C are sufficient.

In the above embodiment, the object of the present invention is achieved even if the design of the detailed structure is changed as appropriate. For example, the channel brush 10 may be used alone or in the form of a triple brush unit according to the thickness of the cylindrical roll 101.

The shapes and dimensions of the mounting members 3, 5, 6 and the mounting intervals may be appropriately selected so as to be most suitable for the size of the cylindrical roll 101 and the use of the brush roll 100.

[0042]

As is clear from the above description, the brush roll having the assembly structure according to the present invention has the following practically superior effects as compared with the conventional brush roll of the same type. (A) The time and labor required to replace a damaged channel brush with a new one can be remarkably reduced as compared with a case where each channel brush is directly welded to a roll shaft. Further, there is no danger of falling off due to poor welding. (B) A gap formed between adjacent channel brushes, which is a major drawback of the conventional type in which a channel brush is inserted into an insertion channel welded to a roll shaft or a channel brush is spirally wound around a roll shaft. However, the problem that causes poor polishing can be solved. (C) Since there is no gap between the channels of the adjacent channel brushes and the bristle material can be densely planted uniformly on the entire outer peripheral surface of the cylindrical roll, the entire surface to be polished can be polished very uniformly. (D) Since the mounting of the channel brush to the cylindrical roll is all performed by screwing, the problem of the method of locking and fixing in a sliding manner using a hook member, which is a problem that the fixing is likely to be uncertain, is almost eliminated. It can be completely solved. (E) Since the top of the countersunk bolt for fixing the channel brush is pressed by the back surface of the adjacent channel brush, the vibration of the brush roll is reliably suppressed by the polishing vibration and pressure of the brush roll. I can do it. (F) Therefore, stress fatigue around the bolt holes can be prevented, and the life of the brush roll can be greatly extended. (G) Since attaching and detaching of the channel brush to and from the roll shaft is all that is required only by screwing and unscrewing operations, even a beginner of the operation can quickly and reliably perform the operations. (H) By mounting the channel brush obliquely with respect to the roll axis, a large polishing pressure does not have to be applied all at once over the entire length of the channel brush.
