Description

Detailed Description of the Invention (Industrial Application Field) The present invention is applicable to super calendars, laminators, IJI
This invention relates to a cleaning device for cleaning the surface of a roll used in an IQ machine or the like.

(Prior art) When pressing, calendering, etc. of magnetic tape, paper, and various films is performed using a super calendar, laminator, film-forming machine, etc., when several pieces of magnetic tape are processed, dust etc. may adhere to the roll surface. Dirt often occurs. When processing with super calenders, laminators, film forming machines, etc., the finishing precision of the product is very strict and the smoothness of the roll surface is extremely difficult. There is a problem that quality is impaired and defective products are more likely to occur. For this reason, conventionally, when the roll surface becomes dirty, the machine operation is stopped and the roll surface is cleaned manually.

(Problems to be Solved by the Invention) However, manual cleaning requires a corresponding number of man-hours, and there is a problem that the operation rate of the machine decreases because it is necessary to stop the operation each time. Note that it has been conventional practice to remove dirt by rubbing the roll surface of paper machine dryers, etc., where the roll surface does not have very strict smoothness, with a blade or with a brush roll. In this case, there are problems in that the roll surface is scratched by the blade and the smoothness of the roll surface is deteriorated, or that dirt removed by the brush travels through the air and re-adheres to the roll surface.

(Means for Solving the Problems) The present invention has been developed based on the above-mentioned problems, and the present invention has been developed by a cleaning device that enables cleaning the roll surface in an IM system while the machine is in operation, without stopping the operation of the machine such as a super calender. To achieve this, the following leaning device is used.

That is, in the cleaning device of the present invention, the belt-shaped cleaning material made of a material softer than the surface of the roll is sent out from the delivery means, and the delivered cleaning material is wound up by the winding means, and the delivery means and the winding means are connected to each other. The cleaning material is pressed onto the roll surface by the pressing means disposed between the cleaning materials, and dirt on the roll surface is collected by the cleaning material. The vacuum means is configured to apply negative pressure to suck dirt on the roll surface collected by the cleaning material from the cleaning material or to hold it on the cleaning material.

(Function) When the above-mentioned leaning device is used, the cleaning material is pressed onto the roll surface by the pressing means while the roll is rotating, and the pressed cleaning material can wipe and collect dirt on the roll surface. Due to the negative pressure applied to the cleaning material by the vacuum means, the dirt collected on the cleaning material can be suctioned away from the noning material or retained in the cleaning material as it is. Therefore, the roll surface can be reliably cleaned even during roll operation. In this case, the cleaning material used is a material that is softer than the hardness of the roll surface, so that the roll surface will not be scratched.

(Embodiments) Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a state in which a cleaning device r110 for cleaning the surface of the roll 1 is attached to the roll 1. The roll 1 is a metal roll, an fMm roll, or the like, and the rotating shaft 1a of the roll 1 is rotatably supported by supporting means 2a and 2b at both ends thereof. 3 in the figure is a base on which calendering and other processes are performed by this roll 1.

A cleaning device 10 is disposed opposite a portion of the surface of the roll 1 that is not in contact with the base 3. FIG. 2 is a cross-sectional view of this cleaning device 10 taken along the arrow I-IF, and the cleaning device 10 will be described below with reference to FIGS. 1 and 2.

This cleaning device 'r1io includes a feed roll 20 as a feed means, a winding means 21 consisting of a winding roll 22 and a winding motor 23, and a vacuum means 30 that
It is configured by being attached to 1. The delivery roll 20 extends diagonally upward from both ends of the upper end of the base 11 and extends from the base a11.
It is rotatably supported by a pair of first arms 12a and 12b fixedly attached to the base, and is made of a non-woven fabric (for example, synthetic fibers such as rayon are dispersed in a short tan and bonded with a binder and heat to form a fabric). Strip-shaped cleaning material 1
9 is wrapped around it.

The take-up roll 22 extends obliquely downward from both ends of the lower end of the base 11 and extends f! It is rotatably supported by a pair of second arms 15a and 15b fixedly attached to 11111, and is driven by a winding motor 23 to wind up the cleaning material 19 sent out from the delivery roll 20. The vacuum means 30 includes upper and lower plates 32a, 32b and a no.L
It has a box projecting toward the roll 1 by the right side k 31a, 31b, and a suction 4433 made of wire mesh, porous material, etc. is attached to the front surface of this box.

Furthermore, a base 35 having a hole that communicates with the inside of the box is fixed on the right side plate 31a of this box. Negative pressure from a suction pump or the like is applied to this base 35 through a hose or the like to create a negative pressure inside the box. It is now possible to apply pressure.

Further, above and below the vacuum means 30, there are a pair of third and fourth arms 13a, 13b, 15a, and 15b, which are fixed to the base 11 and protrude rightward in the figure.
Idle rollers 14a and 14b are rotatably supported by rollers 3a, 13b, 15a and t5b, respectively. Here, the cleaning material 19 wound around the delivery roller 20 is guided through the front side of the vacuum means 30 by the idle rows 514a and 14b, and the cleaning material 19 is wound around the take-up roller 20.
It is wound up in 2. On the other hand, Moto! fill is the support plate 25
The front and rear (second
The FA911 is supported so as to be movable in the direction of the arrow in the figure, and the air cylinder 28 moves the FA911 toward the roll 1, and the suction plate 33 of the vacuum means 30 forces the cleaning material 19 onto the surface of the roll 1. It looks like this. That is, the air cylinder 28 functions as a pressing means. Note that the support plate 25 is a support plate o.
-7 is slidably supported in the lateral direction by support rods 43 and 44, which will be described later, via rips 26a, 26b, 27a, and 27b.

Next, a description will be given of the scanning device 40 that supports the cleaning device 10 configured as described above so as to be movable laterally (in the direction of arrow B in FIG. 1) via the support rods 43 and 44.

This scanning device 40 includes a support frame 4 fixedly held by a pair of eleventh rackets 5a and 5b fixed to support means 2a and 2b that rotatably support the roller 1.
1, and supports a pair of upper and lower support rods 43, 44 that are supported by a pair of second brackets 42a, 42b fixed to both sides of the support frame 41 and extend laterally. The support plate 25 of the cleaning device 10 is attached to the support block 26a on this support rod 43,44 as described above.
, 26b, 27a, 27b so as to be slidable laterally (in the direction of arrow B).Furthermore, between this support plate 25 and the second brackets 42a, 42b, as shown in FIG. A chain or bell 1-45 is provided, and by feeding this chain or belt 45 by a lateral feed motor 4G, the support plate 25 can be moved in the lateral direction, and the cleaning device 10 can be scanned in the lateral direction. It looks like this.

The operation of cleaning *e when cleaning the surface of the roll 1 using the cleaning device 10 configured as described above will be described below.

[, 1-When base 3 such as magnetic tape is sent by rule 1 and calendar processing etc.
The air cylinder 28 supporting the roll 1 is activated, the rod 28a of the air cylinder 28 is extended, and the base 11 is pushed out toward the roll 1 (rightward in FIG. 2). As a result, the suction plate 33 of the vacuum means 30 presses the cleaning material 19 on its front surface against the surface of the roller 1. Note that the pressing force of the air cylinder 28 at this time is 1
It is preferable that the pressure is about 50 gr/cm to 700 gr/cm (linear pressure). In this way, while the cleaning material 19 is being pressed against the surface of the roll 1, the cleaning material 19 is sent out from the delivery roll 20 and wound up on the take-up roll 22,
The cleaning material 19 pressed by the suction plate 33 of the vacuum means 30 is rubbed against the surface of the roll 1 to wipe away dirt on the surface of the roll 1. At this time, the cleaning material 19 is fed in the second direction.
In the figure, the rotation direction of the roll 1 is clockwise (in the direction of arrow C), and the cleaning material 19
move in the opposite direction.

In this case, the speed of the roll 1 is, for example, 300 m/min-aX, and the feeding speed of the cleaning material 19 is, for example, 1 to 1100 a/min.

When the cleaning material 19 wipes off dirt on the surface of the roll 1 in this manner, the vacuum means 30 is activated and negative pressure is applied from the base 35 into the box. This negative pressure acts on the cleaning 4419 on the front side of the suction plate 33 through the suction plate 33 made of a wire mesh, porous material, or the like. Since the cleaning material 19 is made of non-woven fabric, the negative pressure acting on the cleaning material 19 may cause the dirt wiped off the surface of the roll 1 by the cleaning material 19 to be sucked into the box or to be absorbed into the cleaning material 19. or hold it. Therefore, it is possible to prevent dirt wiped off from the surface of the roll 1 by the cleaning material 19 from floating outside and causing IC damage. Note that the cleaning material 19 may be any material as long as it can transmit the negative pressure from the suction plate 33 as described above and also be able to wipe away dirt by rubbing the roll surface without causing piles. In addition to non-woven fabrics, long mwi fabrics, paper, etc. may also be used.

Since the width of the cleaning material 19 of the cleaning device 10 in this example is narrower than the width of the roll 1, in order to clean the entire surface of the roll 1, it is necessary to scan the entire cleaning device 10 in the horizontal direction (in the direction of arrow B). There is. For this reason,
A scanning device 40 is provided, and the supporting plate 25 is moved laterally via a chain 45 by the drive of a lateral feed motor 46, and the entire cleaning MIff 10 is scanned in the lateral direction, so that the entire surface of the roll 1 can be cleaned. It has become. However, this applies when the width of the cleaning material is narrow as in this example, and when the cleaning material moves across the same width as the roll 1, the scanning device is not necessary.

In addition, in this example, a dry cleaning method was described in which the cleaning material was pressed onto the roll surface without any treatment, but a spray device was installed to spray a solvent or the like onto the roll surface to remove dirt. Of course, it is also possible to use a wet cleaning method in which cleaning material is used to make cleaning easier.

Further, although an example is shown in which an air cylinder is used as the pressing means, mechanical pressing may be performed using a spring or the like instead of the air cylinder.

In the above, an example was shown in which one roll is mn, but when several rolls are used, such as in a calendar device, cleaning ii may be provided for each roll. An example is shown in FIG. In the case of Fig. 3, three rolls 1a, 1b and IC are used, and base 3
is caused to pass between rollers 1a and 1b and between rollers lb and Ic by guide rollers 68 to 6e. And base 3 of each 1 cola la, 1b, 10
A cleaning device 10 is attached to each part that is not in contact with the
are arranged facing each other, and each roller la, lb, 1c is cleaned 15 by each cleaning device 10, respectively.

(Effects of the Invention) As explained above, according to the present invention, the cleaning material is pressed against the roll surface by the pressing means during the operation of the roll, and the cleaning material wipes away dirt on the roll surface and collects it. At the same time, the collected dirt can be removed by suction from the cleaning material or retained by the cleaning material using zero pressure applied to the cleaning material by the vacuum means, so that the dirt on the roll surface can be reliably removed and removed. There is no possibility of re-adhering the dirt that has been removed to the surface of the mouth. Therefore, the roll surface can be kept clean at all times during roll operation, and not only can the operating rate of this roll be increased, but also the defective rate of products processed by this roll can be reduced.
