Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention removes stains (dust and other deposits) on the surface of rolls used in the transportation of paper, cloth, film, thin plates, etc., processing equipment, etc. It concerns roll cleaners.

<Prior Art and Problems Thereof> When the roll surface is soiled, defects in the conveyed product and processing defects often occur.

Conventionally, gauze, a non-woven fabric or the like is applied to the roll surface with a hand or a jig, and if necessary, a stain is removed by using a solvent, a cleaning liquid or the like.

Performing this cleaning by hand while the roll is rotating is a problem in terms of work safety, and the line is stopped or the roll is cleaned at a very low speed to clean the entire surface of the roll, which cannot be frequently performed in terms of production efficiency. . Also, when the area around the roll is clean, dust is generated due to human intervention, which causes a decrease in cleanliness.

It is difficult to obtain a stable removal effect by cleaning using a jig, and the frequency of replacement has been increased to prevent reattachment of collected matter.

<Object of the Invention> An object of the present invention is to remove stains on the surface of the roll in a stable manner when no person is involved and to achieve both work safety and productivity. Further, it is also an object to maintain a predetermined cleanliness level in the cleaned equipment.

The above object of the present invention is achieved by installing a roll cleaner on the roll to be cleaned.

<Structure of the Invention> The gist of the present invention is to hold a cleaning tape composed of a wound non-woven fabric and to sequentially unwind the cleaning tape. A cleaning tape unwinding part, at least the surface of which is rotatable, is made of an elastic material. Consists of elastic rolls,
A cleaning unit that performs cleaning by bringing the cleaning tape sent from the sending unit into contact with the cleaning target roll, a liquid supply nozzle that is provided in the vicinity of the elastic roll of the cleaning unit and faces the cleaning tape, and that supplies liquid to the cleaning tape. A roll cleaner comprising: a cleaning tape winding section for winding a used cleaning tape; and a moving mechanism for moving an elastic roll of the cleaning section forward or backward toward a roll to be cleaned.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First
The figure is an explanatory view showing one example of the roll cleaner of the present invention, and shows the case where the roll to be cleaned (5) is the transport roll of the web (A) in the manufacturing process of the coating type magnetic recording medium.

FIG. 2 is a perspective view showing the main body of the roll cleaner of the present invention with the cleaning tape omitted.

In FIG. 1, a wound material (2) of a cleaning tape (1) is set on an unwinding shaft (2 ') equipped with a brake (not shown) for giving an unwinding tension to the tape. . This part of the wound cleaning tape (1) is called a partial unwinding part.

The cleaning tape (1) passes through the elastic roll (4) of the cleaning unit and is passed through the winding shaft (3) of the winding unit, and the elastic roll (4), the wound material (2) and the winding member (2). Cleaning tape (1) between the shafts (83)
Is provided with auxiliary rolls (7) and (7 ') for sufficiently winding the elastic roll (4).

The winding shaft (3) of the winding unit is connected to a motor (not shown), and the cleaning tape (1) is wound by driving the motor.

The cleaning tape (1) is not particularly limited, and tapes of various materials can be used, but for the transport roll of the web, a nonwoven fabric made of, for example, cellulose fiber is preferably used. Also, depending on the type of dirt,
The cleaning tape (1) is preferably impregnated with a solvent, a cleaning liquid or the like because the removal rate of dirt is improved. In this case, the cleaning tape (1) is preferably impregnated with the liquid supply nozzle ( 9), the solvent or the like may be supplied to the cleaning tape (1) by means such as spraying.

At least the surface of the elastic roll (4) is made of an elastic material such as rubber or urethane, and can be moved so as to come in contact with or retract from the roll to be cleaned (5). By appropriately performing this movement, the cleaning tape (1) on the elastic roll (4) can be brought into contact with or removed from the cleaning target roll (5).

The movement of the elastic roll (4) is performed as in the example shown in FIG.
An unwinding shaft (2 '), an elastic roll (4), a winding shaft (3), etc. are installed in the side plates (8) (8'), and these side plates are moved by the moving mechanisms (6) (6 '), respectively. Can be carried out.

In this case, guide rolls (10) (10 ') (10 ") (10) are provided on the outside of the side plates (8) (8'), and a rail (not shown) is inserted between these rolls. It is desirable to form a slide mechanism in order to make the contact position of the elastic roll (4) accurate, and an air cylinder, a hydraulic cylinder or the like is generally used as the moving mechanism (6) (6 ').

In the example shown in FIG. 2, the entire roll cleaner is designed to move, but in such a case, the brake, motor, etc. connected to the unwinding shaft (2 ′) and the winding shaft (3) respectively Since they are not connected to each other (not shown) through universal joints (11) and (11 '), there is no particular inconvenience.

In order to set the winding material (2) to the unwinding shaft (2 ') and the winding core (3) to the winding shaft (3), the shafts are provided with presser fittings (12) (12'), respectively. The shaft can be removed and replaced at the same time as the wound product (2) by a coupling not shown.

Further, the elastic roll (4) may be moved by appropriately adopting, in addition to the above-described overall movement type, a type in which only the elastic roll (4) is directly moved via a bearing mechanism of the elastic roll (4). .

The positional relationship between the unwinding shaft (2 ') and the winding shaft (3) is not particularly limited as long as the cleaning tape (1) can be passed through the elastic roll (4).
For example, it is possible to set the position opposite to the state shown in FIGS. 1 and 2, but the dirt collected on the cleaning tape (1) on the upper surface of the elastic roll (4) is again cleaned (5). To prevent it from sticking to the surface,
As in the example shown in the figure, the cleaning tape (1) on the elastic roll (4) is moved toward the cleaning target roll (5).
It is desirable to provide each shaft in a direction opposite to the rotation direction of the surface of the shaft.

Further, the roll cleaner of the present invention can be applied to rolls to be cleaned having various materials and uses, but is particularly suitable for cleaning web transport rolls in the manufacturing process of the coating type magnetic recording medium, and such use In this case, it is preferable to install the entire cleaner of the present invention in a cleaned facility.

<Effects of the Invention> According to the device of the present invention, stains on the roll surface can be removed at a stable time when necessary without human intervention, and work safety and productivity can be compatible. Further, when installed in a clean equipment, the dirt of the roll is automatically removed and no operator's entry is required, so that a high degree of cleanliness of the equipment can be maintained.
